The direct C-H arylation and acylation of azoles with carboxylic acids were achieved through Pd/Cu cooperative catalysis. Various biaryls and biaryl ketones were selectively produced in good to high yields from the same substrates. The key factor of high chemoselectivity was the choice of a suitable phosphine ligand: biaryls were generated selectively with dppp as the ligand, while biaryl ketones were obtained with high selectivity using dpph or Ph2PCy as the ligand.

I found the field of Chemistry very interesting. Saw the article Anchimerically Assisted Selective Cleavage of Acid-Labile Aryl Alkyl Ethers by Aluminum Triiodide and N,N-Dimethylformamide Dimethyl Acetal published in 2020.0. Category: isothiazole, Reprint Addresses Sang, DY; Tian, J (corresponding author), Jingchu Univ Technol, Coll Chem Engn & Pharm, Jingmen 448000, Hubei, Peoples R China.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde

Aluminum triiodide is harnessed by N,N-dimethylformamide dimethyl acetal (DMF-DMA) for the selective cleavage of ethers via neighboring group participation. Various acid-labile functional groups, including carboxylate, allyl, tert-butyldimethylsilyl (TBS), and tert-butoxycarbonyl (Boc), suffer the conditions intact. The method offers an efficient approach to cleaving catechol monoalkyl ethers and to uncovering phenols from acetal-type protecting groups such as methoxymethyl (MOM), methoxyethoxymethyl (MEM), and tetrahydropyranyl (THP) chemoselectively.

Trace volatile organic compounds (VOCs) such as aldehydes and aromatics significantly deteriorate the indoor air quality especially in newly-decorated buildings. The universal water vapor would greatly decrease the adsorption capacity of ad-sorbents for trace VOCs via competitive adsorption and capillary condensation. Herein, we developed a strategy to subsequently modify the internal and external surface of CAU-1, an aluminum-based metal-organic framework (MOF), to significantly improve its humidity resistance. First, anhydrides were used to transfer amino groups of CAU-1 into hydrophobic groups via amide reaction. Second, polydimethylsiloxane was used to form a hydorphobic coating on its external surface. The adsorption capacity of as-modified CAU-1 for 1 ppm toluene increased about 6 times under 50% relative humidity (RH) at 298 K, even much higher than those of common adsorbents including hydrophobic ZSM-5. In addition, it could be completely regenerated below 373 K, about 65 K lower than that required for regenerating ZSM-5 under the same condition, which not only greatly reduces the energy consumption but also improves the safety and feasibility of in-situ regeneration of adsorbents in indoor environment.

The chemical composition of essential oils (EOs) isolated by hydrodistillation from Pterocarpus soyauxii Taub. root wood and root bark were determined for the first time by GC/MS analysis. The EOs gave a percentage yield (w/w) of 0.34 % and 0.31 % for root wood and root bark respectively. A total of 60 compounds accounting for 86.1 % of the root wood EO composition were identified with monoterpenes (45.4 %) and sesquiterpenes (14.7 %) as predominant constituents. Root bark EO gave 53 identified constituents which make up about 78.5 % of the EO dominated by non-terpenes (23.4 %) and alkanes (14.1 %). The EOs are good sources of limonene (16.9 %), gamma-terpinene (9.8 %) and p-cymene (6.70 %). The anti-diabetic (alpha-amylase and alpha-glucosidase models) and antioxidant activities (DPPH and H2O2 models) of EOs were evaluated in comparison with standard drugs. Alpha-amylase inhibition gave IC50 values (mg/mL) of 0.0493 and 0.0471 for root wood and root bark EOs respectively, compared to acarbose the standard anti-diabetic drug (0.0401) while alpha-glucosidase assay gave IC50 values (mg/mL) of 0.0517 and 0.0486 for root wood and root bark EOs respectively, compared with acarbose (0.0418). In the DPPH antioxidant assay, root bark EO showed higher activity (0.157 mg/mL) compared to root wood EO (0.159 mg/mL) while Root wood and root bark EOs had IC(50 )values (mg/mL) of 0.157 and 0.171 respectively using the H2O2 model. Results revealed the presence of chemical constituents in the EOs which could be responsible for activities expressed by the plant.

Application In Synthesis of Benzoic anhydride. I found the field of Chemistry very interesting. Saw the article Stereo- and Regioselective Synthesis of O-Mannosyl Glycan Containing Matriglycan and a Part of Tandem Ribitol Phosphate published in 2020, Reprint Addresses Tamura, JI (corresponding author), Tottori Univ, United Grad Sch Agr Sci, Tottori 6808553, Japan.; Tamura, JI (corresponding author), Tottori Univ, Grad Sch Sustainabil Sci, Dept Agr Sci, Tottori 6808553, Japan.. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride.

We herein successfully synthesized two pivotal structures of O-mannosyl glycan: (1) the matriglycan-repeating tetrasaccharide Xyl alpha 1-3GIcA beta 1-3Xyl alpha 1-3GlcA beta and (2) the link between matriglycan and a part of tandem ribitol phosphate, Xyl alpha 1-3GlcA beta 1-4Xyl beta 1-4Rbo, in a regio- and stereocontrolled manner. The disaccharide unit with the alpha-linkage of xylose was obtained by adopting the conformational fixation of the xylopyranoside ring and a specific solvation system of diastereoselective solubility.

An article Proton-Coupled Oxidation of Aldimines and Stabilization of H-Bonded Phenoxyl Radical-Phenol Skeletons WOS:000498288300014 published article about AUXILIARY BASIS-SETS; DENSITY-FUNCTIONAL METHODS; ZETA VALENCE QUALITY; GAUSSIAN-BASIS SETS; HIGH-FREQUENCY EPR; RIBONUCLEOTIDE REDUCTASE; GALACTOSE-OXIDASE; CORRELATION-ENERGY; CRYSTAL-STRUCTURE; PHOTOSYSTEM-II in [Samanta, Debasish; Saha, Pinaki; Ghosh, Prasanta] RK Mission Residential Coll, Dept Chem, Kolkata 700103, India in 2019.0, Cited 113.0.

Stable phenoxyl radicals H-bonded to phenols were successfully isolated. The effect of the intermolecular Hbonding to the concerted proton coupled electron transfer (CPET) reactions of the aldimines and the stability and spin distribution of the H-bonded phenoxyls are reported. Salts of iminium-phenol derivatives as cations and the corresponding imine-phenolato derivatives coordinated to zinc(II) as anions, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+), were isolated, where ArOH are aldimine derivatives. Notably, [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts undergo CPET reactions in air affording phenoxyl analogues, [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN. [Zn-II((ArO)-O-R)Cl-2](-)[(ArOH2)-O-R](+) salts incorporate intermolecular iminium-phenolato, [(Zn)Ar-O–+HN=CH-] H-bonds, while [Zn-II(ArOH)Cl-2]center dot ArO center dot center dot CH3CN moieties contain intermolecular phenoxyl-phenol, [Ar-O-HO-Ar](center dot), H-bonds. The phenoxyls are presented in two forms, [(Zn)Ar-O-center dot—HO-Ar (zinc phenoxyl) <-> (Zn)Ar-OH—O-center dot-Ar (free phenoxyl)]. In crystals, the spin density scatters on both phenolic fragments corresponding to a delocalized state, while in solution the latter form has been calculated as a ground electronic state. The X-band EPR spectra of crystals, solutions and frozen glasses were analyzed. The powder spectra at g = 2.0030 +/- 0.0005 and the frozen glass spectra at g = 2.0075 +/- 0.0003 follow the hyperfine patterns due to N-14 (I = 1) nuclei. In fluid solutions, the g values of the hyperfine signals due to (14) N and H-1 nuclei are 2.0078 +/- 0.0001. 1-3 exhibit absorption bands at 350-390 nm due to pi ->pi* intraligand charge transfer (ILCT) transitions, while the radical species, in addition to pi ->pi transitions at 405-440 nm, display phenol to phenoxyl intervalence charge transfer (WCT) transitions at 600-650 nm. The cyclic voltammograms (CVs) of 1-3 depend on the scan rates; at lower scan rates (100-400 mV/s) the CPET reactions occur at -0.92 to -0.96 V versus Fc(+)/Fc couple, whereas at higher scan rates (1000-2400 mV/s), the oxidation occurs by the electron transfer (ET) path at 0.05-0.12 V. Thus, a potential shift of similar to 1.0 V is recorded due to CPET reactions facilitated by H-bonding.
