in the preparation of a number of previously known vinyl compounds, as well as of the new STAB(CH = CH/sub 2/)/sub 4/!/sup -/ and STAB(CH ~ CH/sub 2/ ) (C/sub 6/H/sub 5/)/sub 3/!/sup -/ ions, is described. (auth)
苯基锂和四乙烯基锡(摩尔比为 4:1)在醚中发生的金属转移反应以良好的收率生产乙烯基锂。正丁基锂和四乙烯基锡在戊烷中也会发生类似的反应;在这种情况下,固体乙烯基锂沉淀。乙烯基锂在乙醚和四氢呋喃溶液中比正丁基锂或苯基锂更稳定。乙烯基锂在制备许多先前已知的乙烯基化合物以及新的 STAB(CH = CH/sub 2/)/sub 4/!/sup -/ 和 STAB(CH ~ CH/sub 2) 中的用途/ ) (C/sub 6/H/sub 5/)/sub 3/!/sup -/ 离子,进行了描述。(授权)
