A synthesis of novel selenium heterocycles based on the reaction of selenium dichloride with divinyl sulfide has been described. At −50 °C the reaction affords 2,6-dichloro-1,4-thiaselenane in quantitative yield. At room temperature the reaction gives 2,6-dichloro-1,4-thiaselenane and 5-chloro-2-chloromethyl-1,3-thiaselenolane. Upon standing in chloroform solution, 2,6-dichloro-1,4-thiaselenane undergoes
已经描述了基于二氯化硒与二乙烯基硫的反应合成新型硒杂环的方法。在-50℃下,反应以定量收率得到2,6-二氯-1,4-硫代噻吩烷。在室温下,该反应产生2,6-二氯-1,4-噻吩戊烷和5-氯-2-氯甲基-1,3-噻吩戊烷。在氯仿溶液中放置后,2,6-二氯-1,4-硫代噻吩戊烷自发重排为5-氯-2-氯甲基-1,3-硫代噻吩戊烷。在吡啶的作用下,以95%的产率将2,6-二氯-1,4-硫代噻吩烷转化为2-氯甲基-1,3-硫代噻吩酚。
