Photoexcited electron-hole pairs on a semiconductor surface can engage in redox reactions with two different substrates. Similar to conventional electrosynthesis, the primary redox intermediates afford only separate oxidized and reduced products or, more rarely, combine to one addition product. Here, we report that a stable organic semiconductor material, mesoporous graphitic carbon nitride (mpg-CN), can act as a visible-light photoredox catalyst to orchestrate oxidative and reductive interfacial electron transfers to two different substrates in a two-or three-component system for direct twofold carbon-hydrogen functionalization of arenes and heteroarenes. The mpg-CN catalyst tolerates reactive radicals and strong nucleophiles, is straightforwardly recoverable by simple centrifugation of reaction mixtures, and is reusable for at least four catalytic transformations with conserved activity.

Quantitative structure-activity relationship models are used in toxicology to predict the effects of organic compounds on aquatic organisms. Common filter feature selection methods use correlation statistics to rank features, but this approach considers only the correlation between a single feature and the response variable and does not take into account feature redundancy. Although the minimal redundancy maximal relevance approach considers the redundancy among features, direct removal of the redundant features may result in loss of prediction accuracy, and cross-validation of training sets to select an optimal subset of features is time-consuming. In this paper, we describe the development of a feature selection method, Chi-MIC-share, which can terminate feature selection automatically and is based on an improved maximal information coefficient and a redundant allocation strategy. We validated Chi-MIC-share using three environmental toxicology datasets and a support vector regression model. The results show that Chi-MIC-share is more accurate than other feature selection methods. We also performed a significance test on the model and analyzed the single-factor effects of the reserved descriptors.

para-Quinone methides bearing an electron-withdrawing cyano group at the exocyclic methylene delta-position were identified as valuable 1,6-conjugate addition building blocks for acyclic all-carbon quaternary stereocenter construction. A wide variety of electron-rich arenes as nucleophiles were tolerated, effectively furnishing diverse unsymmetrical triarylmethanes bearing all-carbon quaternary stereocenters. The robust transformable abilities of the cyano group provide a platform to access other valuable functional group-containing unsymmetrical tri- and tetraarylmethanes that are otherwise difficult to be prepared. Computational studies supported the hypothesis that the cyano group at the delta-position tunes the molecular electron-density distribution, and the stability of para-quinone methides is enhanced by lowering their polymerizability.

Although methyl transfer reactions are important in both chemical and biological systems, there is a need for thermodynamic parameters related to methyl affinity and O-CH3 bond dissociation enthalpies (BDEs) relevant to a full understanding of the mechanisms of methyl transfer reactions. As a prelude to the construction of a database of O-CH3 BDEs, the present work examines the reliability of a series of theoretical methods for the prediction of O-CH3 BDEs using a set of 25 compounds that included both aromatic and non-aromatic molecules. The BDEs calculated by density functional theory (DFT) with traditional exchange-correlation functions exhibited much larger errors than those obtained by either the M06-2X or G4 methods. For the non-aromatic compounds, M06-2X/def2-TZVP performed slightly better than G4, but G4 was more accurate for the aromatic molecules. As a result, we recommend G4 as the preferred method for the theoretical estimation of O-CH3 bond dissociation enthalpies, although M06-2X may be a good alternative for large complex molecules when the use of G4 is impractical.

An efficient strategy for the synthesis of all carbon quaternary centres has been developed via Bronsted acid-promoted highly regioselective intermolecular Friedel-Crafts reactions of heteroarenes or arenes with spiro-epoxyoxindoles. In addition, we have successfully performed the ring opening reaction in relatively cheap condition using water as a solvent. Beneficially, we have utilized the methodology as the key step for the synthesis of advanced precursors of various natural and unnatural indole alkaloids.

An investigation of the unexpected lability of the Csp(3)-Csp(2)bond connecting 2,4,6-trimethoxyphenyl group and an allylic moiety is carried out. We observed that the catalytic presence of either Lewis or Bronsted acid can render such 2,4,6-trimethoxyphenyl group labile. Several nucleophiles were found to substitute the labile C-C bond in mild reaction conditions resulting in very good yields of the allylated products. Even in the absence of a nucleophile, intramolecular cyclization of the parent substrate under acidic activation caused the labile C-C bond to cleave. A major motivation of this study is to understand the lability of electron-rich aryl group in acidic medium, employing 2,4,6-trimethoxyphenyl moiety as a case study. A plausible mechanism is proposed after carrying out several control reactions as well as UV/Vis and(1)H NMR spectroscopic studies. This work provides an insight into the activation of electron-rich arenes as a labile entity in acidic medium while also adding a conceptually novel C-C bond breaking approach to the vast literature of allylation of arenes.

The degradation of organic contaminants in aquatic systems has raised immense attention worldwide, and the second-order rate constant (k(SO4)(-)) of water pollutants oxidized by sulfate radical anion is an important index for assessing the degradation efficiency of organics. Herein, a new norm mathematical formula is defined. Based on this, four new descriptors are proposed and a QSPR model is developed for predicting k(SO4)(-) using 30 families of emerging organic pollutants in water. The statistical results fully prove that this model has good fitting effect and stability with R-2 of 0.8862, Q(LOO)(2) of 0.8466, and Q(5-fold)(2) of 0.8329, respectively. The validation results including cross validation, applicability domain analysis, and model comparison show that this model has good robustness, predictive performance, and reliability. These decent results indicate that the new norm mathematical formula is effective in calculating descriptors and the norm indexes have a great application for evaluating the transformation fate of organic pollutants by sulfate radical in aquatic systems.

Enantioselective electrophilic three-component thioarylation of alkenes by chiral selenide catalysis with free phenols as arylating sources is disclosed. A variety of chiral phenols were achieved in high regio-, enantio-, and diastereoselectivities. Mechanistic studies revealed that this transformation went through carbon nucleophilic attack to give the products rather than the process of intramolecular rearrangement of phenolic ether intermediates. The application of this organocatalytic method in the alkylation of methoxy-substituted benzenes elucidated its generality.
