supporting information, p. 11163 - 11167 (2021/04/19)
The electrophotocatalytic heterofunctionalization of arenes is described. Using 2,3-dichloro-5,6-dicyanoquinone (DDQ) under a mild electrochemical potential with visible-light irradiation, arenes undergo oxidant-free hydroxylation, alkoxylation, and amination with high chemoselectivity. In addition to batch reactions, an electrophotocatalytic recirculating flow process is demonstrated, enabling the conversion of benzene to phenol on a gram scale.

ortho -C-H bond halogenation of anilides and N -aryl carbamates using easily available N -halosuccinimides (NXS) as the active halogenation reagent in the presence of nickel or silver catalyst has been developed. This method provides a new approach to 2-haloanilides and carbamates, which may serve as starting materials for the synthesis of pharmaceutically and biologically active compounds.

The palladium-catalyzed reaction of ethyl 2-bromocarbanilate with trimethylsilylacetylene yielded ethyl 2-(trimethylsilylethynyl)carbanilate, which was treated with sodium ethoxide to give indole.The carbanilates having a methyl or a bromo substituent were similarly transformed to corresponding indole derivatives.Furthermore, pyrrolo- and Pyrrolopyridines were synthesized by this method.Keywords---palladium-catalyzed reaction; trimethylsilylacetylene; ethyl 2-halocarbanilate; ethyl 2-halopyridinecarbamate; ethyl 2-(trimethylsilylethynyl)carbanylate; ethyl o-(trimethylsilylethynyl)pyridinecarbamate;indole;pyrrolopyridine
