The synthesis of aryl phosphonates via nickel and palladium-catalyzed cross-coupling of aryl fluorosulfonates and phosphites is described. The products were obtained in good to excellent yields under mild conditions with broad functional group compatibility, employing either Pd(OAc)(2) and DPEPhos or the readily available NiCl2(dme) and Xantphos as catalytic systems. Noteworthily, the present C(sp(2))-P bond formation method could be applied to the direct conversion of phenols to the corresponding aryl phosphonates in one pot via reaction of phenols with SO2F2 and subsequent palladium-catalyzed cross-coupling.

A new ONO-tridentate Schiff base ligand (H2L) derived from 3-methoxysalicylaldehyde and nicotinic hydrazide was synthesized and characterized by elemental analysis, FT-IR, H-1 NMR, C-13 NMR, UV-Vis, and powder XRD studies. Then, oxovanadium(V) and dioxomolybdenum(VI) Schiff base complexes, VOL and MoO2L, were also prepared and characterized by different techniques. Moreover, the catalytic activities of both complexes were investigated for the synthesis of benzimidazoles, benzoxazoles, and benzothiazoles under reflux conditions as well as through ultrasonic irradiation. The results revealed several advantages of this procedure, including high product yields, short reaction times, facile work-up procedure, simplicity in operation, eco-friendly reaction conditions, and green aspects by avoiding toxic catalysts and solvents.

Preparation of mixed carbonates proceeded in one step from ketones and aldehydes via treatment with NaBH4 in dimethyl or diethyl carbonate solvent at elevated temperatures. This is an efficient and convenient alternative to the traditional two-step sequence of carbonyl reduction to alcohol and subsequent carbonate formation by treatment with an alkyl chloroformate. 25 examples are presented from 49 to 92% yield, highlighting the versatility of this reaction.

As singlet oxygen (O-1(2)) is ubiquitous in the environment, O-1(2)-involved oxidation may play an important role in the transformation and fate of organic pollutants. Accordingly, the reaction rate constants (k(1O2)) of organic compounds with O-1(2) are important to determine the environmental fate and persistence assessment of organic pollutants. However, currently there are limited k(1O2) data available, especially for organic chemicals with different charged (deprotonated/protonated) forms. Herein three quantitative structure-activity relationship (QSAR) models (one comprehensive model and two models for neutral and deprotonated molecules) were created for predicting aqueous k(1O2) values for diversely dissociating molecules. The models include larger datasets (180 chemicals) and have wider applicability domain than previous ones. Molecular structural characteristics (only half-wave potential is present in both models) determining the O-1(2) reaction rate of neutral and deprotonated molecules vary greatly. The comparison results of predicting k(1O2) values of organic compounds at certain pH conditions show that the combination of the QSAR models for neutral and deprotonated molecules has advantages over the comprehensive QSAR model. This work is the first study to predict k(1O2) for a wide variety of neutral and deprotonated molecules and provides an important tool for assessing the fate of organic pollutants in aquatic environments.

Computed Properties of C7H6O2. The Name is 3-Hydroxybenzaldehyde. Through research, I have a further understanding and discovery of 100-83-4.

A series of seven new (1, 3, 6, 7, 10, 12, and 13) and six (2, 4, 5, 8, 9, and 11) known diarylpentanoid analogs were synthesized and assessed for their nitric oxide (NO) and alpha-glucosidase inhibitory activities as well as their antioxidant capacity. Nine compounds (2, 3, 4, 5, 6, 8, 11, 12, and 13) were found to exhibit comparable activity to that of curcumin (IC50 = 13.0 mu M), in which compound 8 has displayed strongest NO inhibitory activity with the IC50 values of 17.5 mu M. Meanwhile, four compounds (1, 7, 12, and 13) were found to possess better alpha-glucosidase inhibitory activity than that of curcumin (30.9 mu M), with the IC50 values ranging from 19.4 to 24.9 mu M. On the other hand, none of the synthesized compounds has achieved better DPPH scavenging activities than that of curcumin, indicating the relatively poor antioxidant potential of desired diarylpentanoid structure. Structure-activity relationship (SAR) study disclosed that the existence of meta-hydroxyphenyl and bromo groups is crucial for antiinflammatory and anti-alpha-glucosidase activities, respectively. Molecular docking study showed that bromo moiety could form additional hydrophobic contacts with alpha-glucosidase, thereby increased the inhibition of diarylpentanoid against alpha-glucosidase. The overall results suggested that diarylpentanoids with poly-meta-hydroxylated phenyl ring and multiple bromo groups may lead to the discovery of new diarylpentanoids with both antiinflammatory and anti-alpha-glucosidase activities.

In the present work, the catalytic potential of natural organo-catalyst thiamine hydrochloride is explored for the synthesis of 1,2,4-triazolidine-3-thiones in aqueous medium. The reaction of thiosemicarbazides with various substrates viz aryl/ heteroaryl aldehydes, isatins, cyclic and aromatic ketones to obtain corresponding 1,2,4-triazolidine-3-thiones have been successfully demonstrated for the first time. The method proposed in this work addresses the green chemistry principles such as biodegradable catalyst, ambient reaction condition, shorter reaction time, high yield of the products, recyclability of catalyst and high atom economy.

A three-descriptor quantitative structure-activity/toxicity relationship (QSAR/QSTR) model was developed for the skin permeability of a sufficiently large data set consisting of 274 compounds, by applying support vector machine (SVM) together with genetic algorithm. The optimal SVM model possesses the coefficient of determination R-2 of 0.946 and root mean square (rms) error of 0.253 for the training set of 139 compounds; and a R-2 of 0.872 and rms of 0.302 for the test set of 135 compounds. Compared with other models reported in the literature, our SVM model shows better statistical performance in a model that deals with more samples in the test set. Therefore, applying a SVM algorithm to develop a nonlinear QSAR model for skin permeability was achieved.

A rhodium-catalyzed tandem intermolecular hydroacylation of terminal alkyne-substituted secondary alcohols with chelating aldehydes and deconjugative isomerization of the resulting alpha,beta-unsaturated ketones for the preparation of synthetically valuable 1,4-diketones is developed. Of note, the completely atom-economical protocol can be extended to the alkynyl alcohols with appropriate carbon chain length, from which 1,5-diketone and 1,6-diketone were obtained involving the short-range deconjugative isomerization. Given its robustness, broad substrate scope, and excellent regioselectivity, this approach provides a promising platform for the synthesis of diverse diketones.
