Reaction of a 2 h -1,2,3-diazaphosphole with ethane-1,2-dithiol

Abstract

Reaction of 2-acetyl-5-methyl-2H-1,2,3-diazaphosphole with ethane-1,2-dithiol at -30°C leads to the formation of 2-acetyl-3-(β- mercaptoethylthio)-5-methyl-1,2,3-diaza-phospholene. On heating, this product forms 2-(β-mercaptoethylthio)-1,3,2-dithia-phospholane, 1,2-bis(1,3,2-dithiaphospholanyl)-dithioethane, and N-acetyl-N'-isopropilidene- hydrazine. © 2013 Copyright Taylor and Francis Group, LLC.
