The reactions of benzoylmethanesulfonyl chloride with various anils (Ar–CH=N–R) in the presence of triethylamine have been studied. It has been found that the corresponding (4+2) and/or (2+2) cycloadducts of benzoylsulfene and the anil were obtained, depending on the nature of the substituents, R, in the anils. The reaction of the chloride with benzylidene-n-propylamine in the absence of triethylamine
已经研究了苯甲酰甲磺酰氯与各种苯胺(Ar-CH=N-R)在三乙胺存在下的反应。已经发现,根据苯甲酰亚砜中取代基R的性质,获得了苯甲酰亚砜和苯甲酰的相应(4+2)和/或(2+2)环加合物。在三乙胺不存在的情况下,氯化物与亚苄基-正丙胺的反应仅产生(2+2)环加合物,而(4+2)环加合物仅在三乙胺存在下获得。在三乙胺的存在下,氯化物与二亚苄基乙二胺反应得到相应的双(4+2)环加合物。
