The reactions of 5-arylimino-4-chloro-5H-1,2,3-dithiazoles with 2 equivalents of stable phosphoranes such as carboethoxymethylene-, acetylmethylene-, 4-chlorobenzoylmethylene-, and cyanomethylenetriphenylphosphoranes in the presence of pyridine in CH₂Cl₂ at room temperature gave a new type of the corresponding phosphoranes with aryliminocyanomethyldithiomethylene moiety as a major product.
