The palladium-catalyzed electrochemical C–H bromination of benzamide derivatives under divided cells is developed, in which NH4Br serves as a brominating reagent and electrolyte. The protocol avoids the use of chemical oxidants and provides an alternative method for the synthesis of aryl bromides.

Here, we report a base-controlled chemo-selective reaction of vinylanilines with alkyl/aryl isothiocyanates to afford quinolino-2-thione and 2-aminoquinoline derivatives. The quinolino-2-thiones could be obtained in high yields in the presence of EtN. Particularly interesting is that the reaction could produce the 2-aminoquinolines in the presence of KPO with high selectivity.

Methods for the synthesis of 1,2,4-triazolidines are scarce. Herein, we report a visible-light-promoted decarboxylative addition cyclization of N-aryl glycines and azobenzenes to access such important compounds. Using commercially available methylene...

N-doped porous carbon (NC) could be synthesized route from sugar cane bagasse, which are sustainable and widely available biomass waste. Preferred NC sample has a well-developed porous structure, the graphene-like...
