Palladium-catalysed carbonylation reactions have been developed in the presence of formic acid as carbon monoxide source. alpha,beta-Unsaturated carboxylic acids and esters were synthesized by the transformation of alkenyl halides in moderate to good yields. The selection of the base proved to be crucial regarding the reaction outcome. A set of various substrates were proven under optimised reaction conditions. Compared to aliphatic alcohols, phenols showed excellent reactivity as O-nucleophiles.

This work reports a simple, metal free and cost-effective protocol for the preparation of tri substituted 1,3,5-triazine using graphene oxide as a carbo-catalyst. Substituted triazine can be synthesized in good to excellent yields under mild reaction conditions. Furthermore, the use of graphene oxide as a catalyst results in a product free from metal traces. Recyclability study shows that it can be recycled up to six cycles without significant loss in catalytic activity. To show the scalability of the developed methodology, gram scale synthesis was also carried out.

An unprecedented Ir-III[df(CF3)ppy](2)(dtbbpy)PF6-catalyzed simple photochemical process for direct addition of amines and alcohols to the relatively less reactive nitrile triple bond is described herein. Various amides and esters are synthesized as the reaction products, with nitriles being the acid equivalents. A mini-library of different types of amides and esters is made using this mild and efficient process, which uses only 1 mol% of photocatalyst under visible light irradiation (lambda = 445 nm). The reaction strategy is also efficient for gram-scale synthesis.

Quality Control of 4-Methoxybenzaldehyde. Sahin, C; Sahin, M in [Sahin, Cigdem; Sahin, Murat] Pamukkale Univ, Art&Sci Fac, Dept Chem, Denizli, Turkey published New iridium complexes(III) bearing 2-phenylimidazo[4,5-f][1,10]-phenanthroline ligand: Synthesis, characterization, electrochemical and photoluminescence studies in 2021, Cited 44. The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5.

Iridium complexes bearing 2-phenylimidazo[4,5-f]-[1,10]-phenanthroline with different substituents (CH3, -CH(CH3)(2), -OCH3, -C6H5) were synthesized and characterized. The effects of different substituents and solvents on the photoluminescence properties of the complexes with [Cl] and [PF6] counter anions have been investigated. The synthesized complexes show high photoluminescence quantum yield due to the extension of the pi-electron conjugation of 2-phenylimidazo[4,5-f][1,10]-phenanthroline ligands. The results indicate that the choice of counter anions ([CI] and [PF6]) has an important influence on the quantum yield of the complexes. In toluene, the compound 4 with phenyl substituent exhibits excimer emission with increasing solution concentrations in the presence of [Cl] counter anion. The linear correlation was observed between the redox potentials of the complexes and Hammett Substituent Constants. The linear correlation can allow the prediction of the effects of substituents on electrochemical studies. (C) 2020 Elsevier B.V. All rights reserved.

Several flexible and rigid analogs of 4H-1,2,4-triazoles (compounds 8a-g and 9a-g) bearing trimethoxyphenyl pharmacophoric unit, were designed and synthesized as potential anticancer agents. The in vitro cytotoxic assay indicated that both flexible and rigid analogs (8 and 9, respectively) can potentially inhibit the growth of cancerous cells (A549, MCF7, and SKOV3), with IC50 values less than 5.0 mu M. Furthermore, compounds 10a-l as regional isomers of compounds 9 exhibited remarkable cytotoxic activity with IC50 values ranging from 0.30 to 5.0 mu M. The rigid analogs 9a, 10h and 10k were significantly more potent than etoposide against MCF7, SKOV3 and A549 cells, respectively. These compounds showed high selectivity towards cancer cells over normal cells, as they had no significant cytotoxicity against L929 cells. In addition, the representative compounds 9a and 10h could inhibit the tubulin polymerization at micro-molar levels. By determining changes in the colchicine-tubulin fluorescence, it was suggested that compound 10h could bind to the tubulin at the colchicine pocket. The molecular docking study further confirmed the inhibitory activity of promising compounds 9a, 10h and 10k on tubulin polymerization through binding to the colchicine-binding site.

Transition metal-catalyzed skeletal rearrangement reactions have rapid advances in organic community. Their development benefits synthetic methodologies by providing versatile and flexible approaches toward special molecular scaffolds with high selectivity. Herein, a gold-catalyzed skeletal rearrangement of alkenes with alkynyl bromides is reported, enabling direct and regioselective generation of more than 50 examples of skeletally diverse tricyclic heterocycles, namely, syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines, with generally good yields. This protocol could tolerate terminal unactivated and internal activated alkenes under air conditions, which is hitherto unreported in gold catalysis and scarcely realized by other metal-catalyzed reactions, thus opening avenues for the regioselective assembly of heterocyclic systems with high efficiency. Aside from examining the scope of this skeletal rearrangement, mechanistic investigations to explain the regioselectivity of forming syn-tetrahydrocyclopenta[b]indoles and benzofuro[3,2-b]pyridines were conducted by systematic theoretical calculations.

Zn(OAc)(2)-mediated Mannich-type reaction was studied for the synthesis of 3,3′-pyrrolidinyl-spirooxindole from L-2,3-dihydro-2-oxotryptophan methyl ester and aldehydes. The study indicates that the Mannich-type spirocyclization is significantly influenced by both the cation and anion of the metal salt, base, stoichiometry, stereoelectronics of aldehyde and temperature. With the enhancement by Zn(OAc)(2), the substrate induced asymmetric reaction works on both aromatic and aliphatic aldehydes but at different temperatures. It could deliver the (2’S,3R,5’S)-pyrrodinyl-spirooxindole with up to 96% of diastereomeric ratio in good yield under optimized conditions. (C) 2021 Elsevier Ltd. All rights reserved.

A direct catalytic asymmetric addition of acetonitrile to aldehydes that realizes over 90 % ee is the ultimate challenge in alkylnitrile addition chemistry. Herein, we report achieving high enantioselectivity by the strategic use of a sterically demanding Ni-II pincer carbene complex, which afforded highly enantioenriched beta-hydroxynitriles. This highly atom-economical process paves the way for exploiting inexpensive acetonitrile as a promising C2 building block in a practical synthetic toolbox for asymmetric catalysis.

The morphology and size of Co-MOF-74 were effectively controlled by adjusting the water portion in DMF-H2O mixed solvent system, and six different Co-MOF-74 samples were successfully obtained. The water content can alter the deprotonation rate of the organic ligand and then change the nucleation rate of crystal, thus regulate morphology and size of Co-MOF-74. The discrepancy of morphology and size has significant effect on texture structure of Co-MOF-74 but without changing their composition. The formation mechanism of crystal growth was proposed by studying the change of reaction solution pH value. These samples exhibit morphology and size dependent catalytic activity in toluene oxidation. The flower-like sample has the best catalytic performance with 12.1% toluene conversion and 63.8% benzaldehyde selectivity. Additionally, the influence of reaction parameters on the catalytic oxidation reaction was also examined. Rearserch on the structure-property relationship of catalyst would be useful for rationally synthesizing novel MOF in heterogeneous catalysis.

A composite film with multiple anti-counterfeiting features was demonstrated by superposing quantum dots (QDs) polymer matrix (film A) and cholesteric liquid crystal film (film B) together. The first-line and second-line anti-counterfeiting characteristics were successfully implemented by employing thermochromic, angular photochromic, and circularly polarized discoloration of film B, respectively. By initiatively utilizing the different relative positions between the fluorescence emission peak (lambda(em)) of film A and the central selective reflection wavelength (lambda(em)) of film B at different temperatures, which resulted in changes in the fluorescence spectra or the different presence of latent patterns, the most important third-line anti-counterfeiting feature was successfully achieved.
