The novel reagent NSCl3 is readily generated by treatment of (NSCl)3 with an excess of SO2Cl2; the reactions of NSCl3 with methacrylonitirle or thioacetamide produce 4-cyanosiothiazole or 5-methyl-1,3,2,4-dithiazolium chloride, respectively, in good yields.
通过用过量的SO 2 Cl 2处理(NSCl)3容易产生新的试剂NSCl 3。NSCl 3与
甲基丙烯腈或
硫代乙酰胺的反应分别以高收率产生
4-氰基噻唑或5-甲基-1,3,2,4-二
噻唑鎓盐。
