摘要
合成了1,3—二[1—(4—甲苯基)乙烯基]苯,1,4—二[1—(4—甲苯基)乙烯基]苯与1,4—二[1—(4—叔丁苯基)乙烯基]苯,及与S—BuLi加成得到的油溶不含醚的双锂引发剂,提供了合成方法,测定了产物结构与双锂引发丁二烯聚合的性能。
Three bis (1-phenyl ethenyl) benzenes as 1,3-bis [1- (4-methyl phenyl ) ethenyl ]benzene, 1,4—bis[1—(4—methyl phenyl)ethenyl]benzene and 1,4-his [1-(4-t-butyl phenyl)ethenyl] benzene, and three dilithiums prepared from these his (1-phenyl ethenyl)benzenes separately with s-BuLi were synthesized, and procedures of these syntheses were provided. Structures of these products were determined. Properties of these oil-soluble and nonether-containing dilithiums used as initiators for butadiene polymerization were also determined
