Abstract
A convenient method for design of novel 6-aryl-5-phenyl-5-oxido-6,7-dihydro[1,3,4,2]thiadiazaphospholo[5,4-c][1,2,4,5]triazaphosphinines was achieved. This method depended on three-component reaction of 5-hydrazino-1,3,4,2-thiadiazaphosphole with aromatic aldehydes and phenyldichlorophosphine in dry THF. The methodology was easy, efficient, catalyst-free and good synthetic procedure.
