A new preparative method for the synthesis of bistetrafluoroborates of 2,3,4,5-tetrasubstituted 1,3,4-thiadiazoliums 5a-e from N, N-dialkyl-N,N-dithioacylhydrazines 1a-e is reported. This reaction is extended to the synthesis of bistetrafluoroborate of 3,5-bis(N,N-dimethyliminium)-1,2,4-trithiolane (7) starting from tetramethyl-thiuram disulfide (6). The mechanism of the reaction is discussed.
本文报道了一种新的制备方法,用于从N,N-二烷基-N,N-二硫代酰肼1a-e合成2,3,4,5-四取代1,3,4-噻二唑鎓5a-e的双四氟硼酸盐。该反应被扩展到从四甲基秋兰姆二硫化物(6)合成3,5-双(N,N-二甲基亚胺)-1,2,4-三硫环戊烷(7)的双四氟硼酸盐。本文讨论了反应机理。
