Ru(III)/dimaval was deposited on chitosan aerogel through the ionic interactions of the proton exchange between the dimaval sulfonic acid and chitosan aerogel amine group. After characterization, the composite was used in the oxidation reaction of certain alkylarenes, aliphatic and benzylic alcohols as well as cyclohexanol. High conversions and excellent selectivities were obtained for the solvent-free reactions using a low catalyst amount under aerobic conditions at 80 degrees C for 2-5 h. The organometallic compound is applicable as a heterogeneous catalyst having high chemical stability and recyclability up to eight times. [GRAPHICS] .

Two tetradentate (NNOP) ruthenium products [{RO-C5H3N-C5H3N-CH(O)-C6H4-PPh2}Ru(CO)(PPh3)]Cl (1: R = Me; 3: R = Ph) were isolated by the reactions of the corresponding ligands with RuHCl(PPh3)(3)(CO). Complex 1 could also be transformed into 2 when heated in THF, through C-OMe bond cleavage. The mechanism of the unusual C-O cleavage in complex 1 was investigated, and the results indicate that it is an S(N)2 mechanism through the attack of trace amounts of neutral H2O. In contrast, in the presence of KOH, the reaction switches to an SNAr chemistry. The bidentate ruthenium isomers [{CH3O-C5H3N-C5H4N}RuH(CO)(PPh3)(2)]Cl (4a and 4b) could undergo similar C-O cleavage, affording product {O-C5H3N-C5H4N}RuH(CO)(PPh3)(2) (5), which reacted with HCl to generate complex [{HO-C5H3N-C5H4N}RuH(CO)(PPh3)(2)]Cl (6). These complexes were tested as catalysts for beta-alkylation of secondary alcohols with primary alcohols, and a series of beta-alkylated 1-phenylethanol derivatives were isolated in high yields.

Fragile cultural relics at underwater archaeological sites are difficult to preserve in situ over long time periods due to the effects of a complex and constantly changing surrounding environment. Thus, extracting the relics from water and preserving them in a controllable environment is of primary importance. In this paper, the technology of temporary reinforcement and extraction of underwater fragile relics with veratraldehyde followed by a process of secondary temporary reinforcement using polyethylene glycol (PEG) was studied. After investigating the melting temperature and permeability of PEGs with different molecular weights, we found that PEG-3000 is an excellent candidate as the secondary reinforcing agent for the extracted relics. In the laboratory, combined with veratraldehyde and polypropylene-fiber cloth as temporary underwater strengthening materials, and selected dispersed beaded jewelry and a broken three-dimensional crock as our research subject, we carried out an entire retrieval process-temporary stabilization and secondary temporary reinforcement, to systematically evaluate the technological aspects of safely excavating fragile underwater relics in the original state. After being extracted from water and subjected to secondary temporary reinforcement using PEG-3000, the beaded jewelry and broken crock retained their underwater shape and arrangement completely. The use of secondary reinforcing agent prevents the removal process of veratraldehyde and enclosed sediment from affecting the state of the relics.

The B3NO2 six-membered heterocycle (1,3-dioxa-5-aza-2,4,6-triborinane = DATB), comprising three different non-carbon period 2 elements, has been recently demonstrated to be a powerful catalyst for dehydrative condensation of carboxylic acids and amines. The tedious synthesis of DATB, however, has significantly diminished its utility as a catalyst, and thus the inherent chemical properties of the ring system have remained virtually unexplored. Here, a general and facile synthetic strategy that harnesses a pyrimidine-containing scaffold for the reliable installation of boron atoms is disclosed, giving rise to a series of Pym-DATBs from inexpensive materials in a modular fashion. The identification of a soluble Pym-DATB derivative allowed for the investigation of the dynamic nature of the B3NO2 ring system, revealing differential ring-closing and -opening behaviors depending on the medium. Readily accessible Pym-DATBs proved their utility as efficient catalysts for dehydrative amidation with broad substrate scope and functional-group tolerance, offering a general and practical catalytic alternative to reagent-driven amidation.

Product Details of 100-51-6. I found the field of Food Science & Technology very interesting. Saw the article A multipronged flavor comparison of Ecuadorian CCN51 and Nacional cocoa cultivars published in 2019.0, Reprint Addresses Rottiers, H (corresponding author), Univ Ghent, Fac Biosci Engn, Dept Food Technol, Lab Food Technol & Engn FTE, Ghent, Belgium.; Rottiers, H (corresponding author), Univ Ghent, Fac Biosci Engn, Dept Biotechnol, Res Grp Mol Biotechnol MOBI, Ghent, Belgium..

Two cocoa types are predominantly being cultivated in Ecuador, the highly appreciated fine Nacional and the high-yielding and disease-resistant CCN51, classified as bulk. With the introduction of foreign germplasm in Ecuador and the international demand for high-quality Nacional cocoa, the present study aims to characterize and compare the flavor profile of Nacional hybrids (EET103, EET559, EET576 and EET577) and CCN51, and to assess the effect of the genotype. The fermented dried beans were processed into liquor and their sensory properties, volatile composition and odor fingerprint were analyzed by trained panelists, headspace-solid phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS), and GC electronic nose (e-nose), respectively, combined with multivariate statistics. Seventy volatiles were identified and semi-quantified, among them, 16 and 14 volatiles conferring fruity and floral aroma notes, respectively. CCN51 was mainly characterized by undesirable odor-active volatiles, whereas the EET cultivars contained the highest concentration of most fruity and floral volatiles, with differences in between EET cultivars. Sensory data highlighted organoleptic differences between the fine and bulk liquors, i.e. the fruity and acid EET flavor strongly differed from the bitter, astringent and off-flavor attributes of CCN51. Principal component analysis (PCA) discriminated firstly between fine and bulk, and secondly between EET identity. Partial least squares analysis identified possible correlations between sensory attributes and volatile compounds. Besides, e-nose proved its usefulness for rapid assessment of the liquors’ sensory profile. The results provide a foundation for understanding the genotype’s contribution to and the compositional basis of Ecuadorian fine and bulk cocoa flavor.

Developing efficient and selective strategies to approach complex architectures containing (multi)stereogenic centers has been a long-standing synthetic challenge in both academia and industry. Catalytic cascade reactions represent a powerful means of rapidly leveraging molecular complexity from simple feedstocks. Unfortunately, carrying out cascade Heck-type reactions involving unactivated (tertiary) alkyl halides remains an unmet challenge owing to unavoidable beta-hydride elimination. Herein, we show that a modular, practical, and general palladium-catalyzed, radical three-component coupling can indeed overcome the aforementioned limitations through an interrupted Heck/allylic substitution sequence mediated by visible light. Selective 1,4-difunctionalization of unactivated 1,3-dienes, such as butadiene, has been achieved by employing different commercially available nitrogen-, oxygen-, sulfur-, or carbon-based nucleophiles and unactivated alkyl bromides (>130 examples, mostly >95:5 E/Z, >20:1 a). Sequential C(sp(3))-C(sp(3)) and C-X (N, O, S) bonds have been constructed efficiently with a broad scope and high functional group tolerance. The flexibility and versatility of the strategy have been illustrated in a gram-scale reaction and streamlined syntheses of complex ether, sulfone, and tertiary amine products, some of which would be difficult to access via currently established methods.

Due to the fact that tyrosinase is responsible for biosynthesis and regulation of melanins and browning food products, tyrosinase inhibitors can be favorable agents in cosmetics and medicinal industries. A series of novel 2-hydroxy-4-methoxybenzohydrazide were designed, synthesized, and their new application as tyrosinase inhibitors was also disclosed. Based on in vitro tyrosinase inhibitory assay, 4d as the strongest inhibitor of tyrosinase with an IC50 value of 7.57 mu M showed approximately 2.5-fold better inhibition than kojic acid as positive control followed by two compounds 4b (IC50 = 8.19 +/- 0.25 mu M) and 4j (IC50 = 8.92 +/- 0.016) which displayed preferable tyrosinase inhibitory activity. Detailed investigations on the mechanism of action of the 4d reported mix type of inhibition. More importantly, molecular modeling assessments proposed the ability of 4d for potential interaction with Cu (metal)-His (residue) within tyrosinase active site. Overall, 4d is a promising candidate for the development of anti-tyrosinase agents.

In spite of the enormous promise that polymeric carbon nitride (PCN) materials hold for various applications, the fabrication of high-quality, binder-free PCN films and electrodes has been a largely elusive goal to date. Here, we tackle this challenge by devising, for the first time, a water-based sol-gel approach that enables facile preparation of thin films based on poly(heptazine imide) (PHI), a polymer belonging to the PCN family. The sol-gel process capitalizes on the use of a water-soluble PHI precursor that allows formation of a non-covalent hydrogel. The hydrogel can be deposited on conductive substrates, resulting in formation of mechanically stable polymeric thin layers. The resulting photoanodes exhibit unprecedented photoelectrochemical (PEC) performance in alcohol reforming and highly selective (similar to 100 %) conversions with very high photocurrents (>0.25 mA cm(-2) under 2 sun) down to <0 V vs. RHE. This enables even effective PEC operation under zero-bias conditions and represents the very first example of a 'soft matter'-based PEC system capable of bias-free photoreforming. The robust binder-free films derived from sol-gel processing of water-soluble PCN thus constitute a new paradigm for high-performance 'soft matter' photoelectrocatalytic systems and pave the way for further applications in which high-quality PCN films are required.

Amberlyst 15 resin supported the tandem reaction of cinnamic acids with phenols under solvent-free reaction condition has been introduced to afford 4-aryl-3,4-dihydrocoumarin (neoflavanone) derivatives. The efficiency of solid acidic sulfonic resin (A-15) has been illustrated in two reaction activation methods such as microwave irradiation and conventional heating. The important roles of Amberlyst 15 have been emphasized strongly through the high yields of 4-aryl-3,4-dihydrocoumarin in the shorter time under the assistance of microwave irradiation than of conventional heating, and its high recovery and reusability for six catalyst runs. The original catalyst as well as the recycled catalyst were characterized by XRD and FE-SEM to study the correlation of the surface of reused catalyst and its recyclability.
