Essential oils (EOs) from anise seeds (Pimpinella anisum) collected in the Algerian region were extracted by microwave-assisted hydrodistillation (MAHD) and hydrodistillation (HD). The oil yield (%), chemical composition, energetic consumption and the antimicrobial properties were evaluated of the obtained EO. The yields obtained by both processes were 2.81 +/- 0.01% for 90 minutes and 3.30 +/- 0.05% for 330 minutes for MAHD and HD, respectively. The determination of the chemical composition of EOs by GC-MS revealed the presence of a majority compound,trans-anethole 81.52% and 91.31% for MAHD and HD, respectively. The other main compounds present in the oils for MAHD and HD were, respectively: methyl chavicol (estragole) (0.63%-1.39%),cis-anethole (0.23%-0.34%), anisaldehyde (1.1%-1.57%), anisyl methyl ketone (0.28%-0.13%),trans-methyl isoellgenol (0.31%-0.17%),gamma-himachalene (0.5%-0.36%),trans-pseudoisoeugenyl 2-methylbutyrate (6.53%-2.53%) and epoxy-pseudoisoeugenyl 2-methylbutyrate (2.01%-0.56%). The EO obtained by MAHD detected other compounds, fenchone 0.41%, limonene 0.68%,cis-jasmolacatone extra C 0.41%,trans-isolongifolanone 0.2% and alpha-himachalene 0.16%. The energetic consumption by MAHD was significantly less than HD. Theoretical data from mathematical modelling were compared with practical data, and the coefficient of determination was between 0.93 and 0.97. The sensibility of bacterial strains to the essential oil obtained by MAHD is marked relatively to that obtained by HD, and for the sensibility of fungal strains, it was conserved. The MAHD process revealed a good yield of anise seeds EOs while reducing extraction time and energetic consumption. The EO extracted by this process revealed the presence of other compounds while improving antibacterial activity.

We have developed a supramolecular (close form) [2]pseudorotaxane polymer containing the green-emissive (lambda(em) = 523 nm) BODIPY-based pillar[5]arene host and the non-emissive spiropyran (SP)-based cyano guest (close form), which can be converted to a red-emissive (lambda(em) = 630 nm) merocyanine (MC)-based guest (open form) upon UV exposure as well as turned into a bi-fluorophoric host-guest polymer with ratiometric PL emission of Forster resonance energy transfer (FRET) behavior in THF/water solution (60% H2O, v/v). The equal host-guest molar ratio and the formation of the [2]pseudorotaxane polymer can be further verified using H-1 NMR titration, Job’s plot analysis, DOSY and ITC experiments. Hence, the bi-fluorophoric host-guest (with the MC open form) polymer possessed the highest red-emission of the MC acceptor, which was also confirmed using TRPL measurements to possess the shortest lifetime of 0.37 ns and the best FRET efficiency of 83.5%. Since the MC unit could react with CN- to induce a non-emissive quenching process, the mono-fluorophoric guest would show turn-off PL behavior and detect cyanide ions with a corresponding limit of detection (LOD) value of 0.94 mu M. In comparison, the optimal LOD value of 0.48 mu M toward CN- anion could be achieved by our bi-fluorophoric host-guest polymer via the FRET-OFF process. Therefore, cyanide detection and cell viability tests using the open form of the [2]pseudorotaxane polymer suggest useful bio-imaging applications in living cells.

Small-ring heterocycles comprising pyrrole and pyrazole are well known for their rich biological properties. In this article, an efficient green sonochemical approach was designed for the synthesis of novel, fully substituted pyrroles connected to pyrazole scaffolds via a one-pot, four-component isocyanide-based sequential reaction. This reaction was carried out using various 5-amino-pyrazoles, aldehydes, dialkyl acetylenedicarboxylates and isocyanides for the synthesis of fully functionalized pyrroles with high chemoselectivity in the presence of a catalytic amount of PTSA center dot H2O, in good to excellent yields under ultrasound irradiation. This waste-free (-H2O) reaction exhibited a high atom economy and step economy via creating four new bonds, including two C-N and two C-C bonds, and the formation of two five-member heterocycles which are connected in a single operation. The mechanism of this four-component domino process involved sequential imination-dipolar cyclization-[1,5]-H shift reactions. The synthesized compounds possess interesting fluorescence features, and the bioactive scaffolds might attract great interest in the fields of clinical diagnostics and biomedical research in the future.

A series of iminophosphorane-thiourea/urea bifunctional catalysts was synthesized and utilized for the isoselective ring-opening polymerization of rac-lactide. The ROPs were promoted efficiently, affording the polylactides with controlled molecular weight, narrow molecular weight distribution and well-defined end groups without undesired side reactions. The experiment data revealed that ROPs of rac-LA are a controlled/living process. The highest stereoselectivity (P-m) was up to 0.80 using rac-IPU-1 under mild reaction conditions. The mechanistic study indicated that stereoselective ROPs of rac-LA were mainly controlled by a chain-end control mechanism when using rac/(R,R)-IPTU-1/IPU-1 as catalysts. Additionally, the ee values of -11% at 0 degrees C and -17% at -40 degrees C were achieved at about 50% conversion using (S)-IPU-2 as a chiral catalyst. The selectivity factor (s = k(L)/k(D)) of 1.6 indicated that a clear kinetic resolution occurred and the enantiomorphic site control mechanism was involved.

Palladium catalysed carboxytelomerisation of 1,3-butadiene with alcohols yields unsaturated C-9-pelargonic esters in an atom-economic and straightforward way. Although carboxytelomerisation is of current interest, limitations of applicable alcohol substrates have not been fully investigated. In here, we present the transfer of the catalytic system comprising palladium acetate and tri-n-butyl phosphine in pyridine to a broad variety of 20 alcohols with vast difference in nucleophilicity and sterical demands yielding the corresponding esters in a 100% atom economic manner. Effects of nucleophilicity and sterical demands were revealed for monoalcohols, di- and polyols. Whilst yields, chemoselectivity and E/Z-selectivity of the pelargonic acid derivatives were excellent with up to 99%, selectivity towards mono-, di- and triesters could be controlled successfully. Finally, the reaction profile of the carboxytelomerisation glycerol was uncovered, yielding up to 97% of industrially relevant unsaturated C-9-short chain fats.

Synthesis of fluorescent molecules has drawn considerable attention due to their potential applications in life and material sciences. Here we report a metal-free approach to a new class of fluorophore, namely, 6-(2-hydroxyarypisoindolo[2,1-a]quinoxalin-11(5H)-ones exploiting ninhydrin ring system via base promoted tandem cyclization. The readily obtainable phenolic adducts of ninhydrin undergoes smooth reaction with o-phenylenediamine in refluxing ethylene glycol/Et3N via breaking of C-C bond, N-insertion, followed by heterocyclization to furnish the fully unsaturated isoindoloquinoxaline framework. Structures of the products are in good agreement with their IR, 1HNMR, (CNMR)-C-13, and mass spectral data. The photophysical properties of the synthesized compounds were studied by UV-vis absorption and fluorescence spectroscopic techniques under ambient conditions, and the results reveal an interesting property of large Stokes shift.

The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Silica was prepared from rice husk-agricultural waste-by soaking and pyrolysis method. Ceria and samaria were impregnated on silica by rotavapor-assisted impregnation method. The physicochemical properties of Ce-Sm/Si catalyst were determined by BET, FT-IR, XRD, SEM, EDX, and n-butylamine titration. Catalytic activity was evaluated by oxidation of benzyl alcohol (Bzl-OH) to benzaldehyde (B-CHO) using H2O2 as an oxidant in acetonitrile medium. Different reaction parameters like time, temperature, solvent, and catalyst amount on the reaction were also studied. Among the various catalysts, 50Ce50Sm/Si showed the impressive catalytic performance with a selectivity of 91.4% to benzaldehyde. The improved catalytic performance was attributed to the well dispersion of ceria-samaria on the surface of silica. These materials can be reused effectively up to four cycles without significant loss in their selectivity. Moreover, excellent selectivity of benzaldehyde in shorter duration using modified rice husk silica catalysts makes this protocol highly attractive and practically beneficial. Graphical abstract

In this study, preparation, characterization and catalytic application of a novel core-shell structured magnetic Tiloaded phenylene-based nanoporous organosilica (Mag@Ti-NOS) nanocomposite are developed. The Mag@TiNOS was synthesized via cetyltrimethylammonium bromide (CTAB) directed co-condensation of tetramethoxysilane (TMOS), tetrabutyl orthotitanate (TBOT) and 1,4-bis(triethoxysilyl)benzene (BTEB) over Mag@ SiO2 under alkaline conditions. This nanocomposite was characterized by using FT-IR, EDX, PXRD, VSM, SEM, TEM, XPS, ICP and TGA techniques. These analyses showed a core-shell structure with high chemical and thermal stability for the designed material. The Mag@Ti-NOS nanocomposite was employed as an effective, powerful and recyclable catalyst in the synthesis of tetrahydrobenzo[b]pyrans in H2O at 50 degrees C under ultrasonic conditions. This catalyst was recovered and reused several times without significant decrease in efficiency and stability. The recovered catalyst was analyzed by FT-IR, PXRD and SEM to study its stability during reaction process.
