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.
5-吡啶基-4-氯-5H-1,2,3-二噻唑与2当量的稳定phosphor烷在CH 2 Cl中在吡啶存在下的反应,如碳乙氧基亚甲基,乙酰基亚甲基,4-氯苯甲酰基亚甲基和氰基亚甲基三苯基膦2在室温下得到一种新型的相应的正膦,其主要成分是芳基氨基氰基甲基二硫亚甲基。
