5,5-Diphenyl-2,4-thiazolidinedithione (3a), when refluxed with anhydrous AlCl3 in toluene, is desulfurated and rearranged to 4,5-diphenyl-4-thiazoline-2-thione (4). Neither 2,2-diphenyl-1,4,2H- benzothiazine-3(4H)-thione (5b) nor its S-Me derivative (6 are changed on similar treatment.
当与无水AlCl 3在甲苯中回流时,将5,5-二苯基-2,4-噻唑烷二硫酮(3a)脱硫并重排为4,5-二苯基-4-噻唑啉-2-硫酮(4)。既不2,2-二苯基1,4,2H-苯并噻嗪-3(4H) -硫酮(图5b),也不其S-我衍生物(6被改变上类似的处理。
