K2S-Mediated Tandem Selenylation and Cyclization of CaC2 with Diselenides: Synthesis of 2-Methylbenzoselenazole

Abstract A concise and efficient one-step strategy for the synthesis of 2-methylbenzoselenazoles has been developed using K2S-mediated reaction of diselenides with calcium carbide (CaC2) as a solid acetylene source. This method features a novel Se–S dynamic exchange mechanism, wh...
