Xu, Jinhui published the artcileUnveiling Extreme Photoreduction Potentials of Donor-Acceptor Cyanoarenes to Access Aryl Radicals from Aryl Chlorides, Formula: C8H11NO, the main research area is aryl chloride boronate light cyanoarene photoreductive borylation catalyst; arylboronate preparation; phosphine aryl chloride light cyanoarene phosphorylation catalyst; arylphosphonium salt preparation.

Since the seminal work of Zhang in 2016, donor-acceptor cyanoarene-based fluorophores, such as 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN), have been widely applied in photoredox catalysis and used as excellent metal-free alternatives to noble metal Ir- and Ru-based photocatalysts. However, all the reported photoredox reactions involving this chromophore family are based on harnessing the energy from a single visible light photon, with a limited range of redox potentials from -1.92 to +1.79 V vs SCE. Here, we document the unprecedented discovery that this family of fluorophores can undergo consecutive photoinduced electron transfer (ConPET) to achieve very high reduction potentials. One of the newly synthesized catalysts, 2,4,5-tri(9H-carbazol-9-yl)-6-(ethyl(phenyl)amino)isophthalonitrile (3CzEPAIPN), possesses a long-lived (12.95 ns) excited radical anion form, 3CzEPAIPN�*, which can be used to activate reductively recalcitrant aryl chlorides (Ered �-1.9 to -2.9 V vs SCE) under mild conditions. The resultant aryl radicals can be engaged in synthetically valuable aromatic C-B, C-P, and C-C bond formation to furnish arylboronates, arylphosphonium salts, arylphosphonates, and spirocyclic cyclohexadienes.

Li, Mingxue published the artcileMechanism and kinetics of ClO·-mediated degradation of aromatic compounds in aqueous solution: DFT and QSAR studies, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is density functional theory degradation chlorine oxide radical wastewater treatment.

The action of ClO· is more prominent than HO· and Cl· in the advanced oxidation degradation of some pollutants. However, studies on the pollutant degradation mechanism and kinetics by ClO· are limited. In this study, 43 different kind of aromatic compounds which are important anthropogenic and natural water pollutants were selected as models to investigate their ClO· oxidation mechanism and kinetics computationally. The results showed that radical adduct formation (RAF) rather than single electron transfer (SET) reaction was prominent in ClO·-initiated reactions of aromatic compounds In subsequent reactions of the ClO-adduct, the Cl end of the -OCl moiety shifted to the benzene ring, which was the key to hydroxylation and chlorination of aromatic compounds by ClO·. The calculated ClO· initiated reaction rate constants (k·ClO) of aromatic compounds were 102-1010 M-1 s-1. ClO· was highly reactive to phenolates, anilines and alkoxy/hydroxyl aromatic compounds Upon the deprotonation of phenol to phenolate, the k·ClO value increased by 4 orders of magnitude. The k·ClO values of alkoxybenzenes were higher for compounds with shorter alkyl side chains and more alkoxy substituents. The k·ClO increased for anilines with longer alkyl side chains. The k·ClO quant. structure-activity relationships (QSARs) models were developed to predict the reactivity of ClO· to complex aromatic compounds in aquatic systems.

Muralirajan, Krishnamoorthy published the artcileExploring the Structure and Performance of Cd-Chalcogenide Photocatalysts in Selective Trifluoromethylation, Application In Synthesis of 151-10-0, the main research area is trifluoromethylated arene oxindole alkene preparation photochem; heteroarene alkene selective trifluoromethylation cadmium selenide catalyst.

The field of heterogeneous photoredox catalysis has grown substantially and impacted organic synthesis because of the affordability and reusability of catalysts. This study reports radical trifluoromethylation with Cd-chalcogenide semiconductors. Cd semiconductors, particularly CdSe, are readily available, com., visible-light-responsive, heterogeneous photocatalysts. The potential of readily available Cd semiconductors, particularly CdSe, is confirmed by their increased photocatalytic activity toward trifluoromethylation with various substrates, such as (hetero)arenes and vinylic amides/acids, via addition, cyclization, and decarboxylation under visible light. The economic significance of this strategy is also highlighted through the scalable synthesis of biol. active mols. followed by catalyst reuse. Moreover, these catalysts are relatively inexpensive compared with transition metal-based homogeneous photocatalysts, presently used in organic synthesis.

In the present study, the gold(I)-catalyzed reaction of 1,5-allenenes was controlled in such a way that instead of a [2+3] cycloaddition, a 5-exo-cyclization with the formation of a carbocation occurred. The latter could be trapped with both oxygen and carbon nucleophiles. In the investigated system, fused tricyclic frameworks I (R = Me; R1 = Me, Cl, Br, etc.; Nu = OMe, OEt, 2-furyl, etc.) with three contiguous stereocenters with excellent chemo- and diastereoselectivity in up to 95% yield were obtained.
