Abstract

New stabel 3H-1,2-benzodithiole derivatives, 3-aryl-3H-1,2-benzodithioles, were synthesized. While the reaction of the 3-aryl-3H-1,2-benzodithioles with CH2I2-Et2Zn gave methylene-inserted products 4-aryl-2,4-dihydro-1,3-benzodithiines, the reaction with dichlorocarbene afforded unexpected products 2-chloro-3-arylbenzo[b]thiophenes.
