几种有机锑(Ⅲ)化合物与共轭极性化合物的反应

REACTIONS OF SOME ORGANOANTIMONY(Ⅲ) COMPOUNDS WITH POLAR CONJUGATE COMPOUNDS

讨论了几种有机锑（Ⅲ）化合物与共轭极性化合物的反应性质．在防湿、防空气的条件下，锑原子上连有亲核原子N，S的Sb（NEt2）3，Sb（SEt）3与共轭极性化合物反应，反应机理被推测为1，4加成反应，而连有烃基的有机锑（Ⅲ）化合物SbPr3，SbPh3不与共轭极性化合物反应．丙烯酸胺与Sb（NEt2）3的反应随后处理方法不同，产物也不同，并且SbPr3，Sb（SPh）3能引发甲基丙烯酸甲酯（MMA）聚合．

This paper discusses the reactivity of some organoantimony (Ⅲ) compounds with polar conjugate compounds. When protected from moisture and air, Sb (NEt2 ), and Sb (SEt )3 in which antimony connected with nucleophilic atoms N,S, reacted with polar conjugate compounds with which trialkylstibine such as SbPr3. SbPh3 did not react. The mechanism of the reaction was conjectured as 1,4 addition reaction. Different methods of aftertreatment in the reaction of Sb (NEt2 ), with acrylicamide gave different products.Moreover, SbPr3 and Sb (SPh)3 could initiate methylmethacrylate to polymerize.
