This article describes a green method for regeneration of carbonyl compounds from various types of oxime compounds under microwave radiation using I-2 and aqueous saponin solution isolated from Shikakai. Effect of saponin concentration on yield percentage of regenerated different types of carbonyl compounds has been discussed. A correlation has been established between saponin concentration and yield percentage of carbonyl compounds. Mechanism of interaction between oxime and saponin is established on the basis of density functional theory. In addition, the quantum chemical parameters for saponin have been determined. Furthermore, electrostatic surface analysis of the saponin is carried out to confirm the mechanism of interaction between saponin and oximes. (C) 2020 Elsevier B.V. All rights reserved.

Nickel(ii)complexes of N-4-ligands have been synthesized and characterized as efficient catalysts for the hydroxylation of benzene using H2O2. All the complexes exhibited Ni2+ -> Ni3+ oxidation potentials of around 0.966-1.051 V vs. Ag/Ag+ in acetonitrile. One of the complexes has been structurally characterized and adopted an octahedral coordination geometry around the nickel(ii) center. The complexes catalysed direct benzene hydroxylation using H2O2 as an oxygen source and afforded phenol up to 41% with a turnover number (TON) of 820. This is unprecedentedly the highest catalytic efficiency achieved to date for benzene hydroxylation using 0.05 mol% catalyst loading and five equivalents of H2O2. The benzene hydroxylation reaction possibly proceeds via the key intermediate bis(mu-oxo)dinickel(iii) species, which was characterized by HR-MS, vibrational and electronic spectral methods, for almost all complexes. The formation constant of the key intermediate was calculated to be 5.61-9.41 x 10(-2) s(-1) by following the appearance of an oxo-to-Ni(iii) LMCT band at around 406-413 nm. The intermediates are found to be very short-lived (t(1/2), 73-123 s). The geometry of one of the catalytically active intermediates was optimized by DFT and its spectral properties were calculated by TD-DFT calculations, which are comparable to experimental spectral data. The kinetic isotope effect (KIE) values (0.98-1.05) support the involvement of nickel-bound oxygen species as an intermediate. The isotope-labeling experiments using (H2O2)-O-18 showed 92.46% incorporation of O-18, revealing that H2O2 is the key oxygen supplier to form phenol. The catalytic efficiencies of complexes are strongly influenced by the geometrical configuration of intermediates, and stereoelectronic and steric properties, which are fine-tuned by the ligand architecture.

A novel approach was achieved for growing citric acid towards polymer-like graphene quantum dots (PGQD) with high efficiency in the presence of sodium hydroxide as a base catalyst. This protocol is completely safe, simple, fast, and efficient by a bottom up strategy. Thermal treatment of a mixture containing citric acid with NaOH at 300 degrees C gave PGQD during 5 min. The reaction afforded a new heterogeneous catalyst, Pd/PdO/Fe3O4@PGQD, in the presence of Pd and Fe3O4. The magnetically recoverable catalyst showed high activity in the oxidation of alkylarenes and alcohols using H2O2 as a green oxidant at room temperature. Comparison of the results with previous reports showed the efficiency of the catalyst to have high turnover numbers in mild reaction conditions.

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.

Simple alpha-(bromomethyl)styrenes can be processed to a variety of 1,1-difluorinated electrophilic building blocks via I(I)/I(III) catalysis. This inexpensive main group catalysis strategy employs p-TolI as an effective organocatalyst when combined with Selectfluor (R) and simple amine center dot HF complexes. Modulating Bronsted acidity enables simultaneous geminal and vicinal difluorination to occur, thereby providing a platform to generate multiply fluorinated scaffolds for further downstream derivatization. The method facilitates access to a tetrafluorinated API candidate for the treatment of amyotrophic lateral sclerosis. Preliminary validation of an enantioselective process is disclosed to access alpha-phenyl-beta-difluoro-gamma-bromo/chloro esters.

The alpha-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective alpha-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl alpha-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection of electrophiles including carboxylic esters and dihalosilanes or germanes, which afford interesting benzofuran, sila(germa)dihydrobenzofuran, and silachroman derivatives from simple aryl benzyl ethers.

An Auxiliary Activity Family 5 (AA5) copper-radical alcohol oxidase (AlcOx) with promiscuous activity towards simple alkyl and aromatic alcohols was evaluated using real-time reaction progress monitoring. Reaction kinetics using variable time normalization analysis (VTNA) were determined from reaction progress curves. By this approach, a detailed view of the entire reaction time course under various conditions was obtained and used to identify parameters that will inform further process optimization development. Optimal activity was found impacted by several factors, including reaction pH, oxygen saturation, and the source of a co-oxidant, either HRP or a chemical alternative, potassium ferricyanide. Analysis of reaction progress curves demonstrated that reaction stalling occurred as a result of oxygen depletion and from a loss of enzyme activity over time. The cooperativity between AlcOx, horseradish peroxidase (HRP), and catalase that result in enhanced reactivity was explored, with reaction pH being identified as a key factor for optimal activity. The results show that a process with HRP is more robust than with potassium ferricyanide, but that both oxidants likely activate AlcOx by a similar mechanism. The phenomenon of product inhibition was investigated for representative reactants, revealing that reaction inhibition was more significant for butyraldehyde than for benzaldehyde. Our analysis suggests that this is linked to the greater proportion in which butyraldehyde exists in the hydrated form.

The FDA (U.S. Food and Drug Administration) has approved only a negligible number of poly(lactide-co-glycolide) (PLGA)-based microsphere formulations, indicating the difficulty in developing a PLGA microsphere. A thorough understanding of microsphere formulations is essential to meet the challenge of developing innovative or generic microspheres. In this study, the key factors, especially the key process factors of the marketed PLGA microspheres, were revealed for the first time via a reverse engineering study on Vivitrol(R) and verified by the development of a generic naltrexone-loaded microsphere (GNM). Qualitative and quantitative similarity with Vivitrol(R), in terms of inactive ingredients, was accomplished by the determination of PLGA. Physicochemical characterization of Vivitrol(R) helped to identify the critical process parameters in each manufacturing step. After being prepared according to the process parameters revealed by reverse engineering, the GNM demonstrated similarity to Vivitrol(R) in terms of quality attributes and in vitro release (f(2) = 65.3). The research on the development of bioequivalent microspheres based on the similar technology of Vivitrol(R) will benefit the development of other generic or innovative microspheres.
