2-Phenyl-, 2-p-tolyl- and 2-p-anisyl-3,1-benzothiazine-4-thiones (Ia-c) react readily with diazomethane yielding the corresponding cis- (IIa-c) and trans- (IIIa-c) 1,3-dithioles.Coumarin-2-thione behaves in a similar manner.Diphenyl- and p,p'-dimethoxydiphenyl-diazomethanes as well as 9-diazofluorene react with Ia-c to give the episulphides.
