By applying four different methods twelve new organoelement substituted pentadienes have been prepared. They contain one or two organoelement groups. - Pentadienyllithium (2) reacted with Cl-SPh, Br-SePh, Cl-PPh2, and Cl-AsPh2 (lone pair at the element) exclusively to the corresponding E-1-(organoelement)-2,4-pentadiene, whereas with Cl-MMe3 (M = Si, Ge, Sn) (2,3,4), Cl-GePh3, and Cl-SnPh3 (no lone
通过应用四种不同的方法,已经制备了十二种新的有机元素取代的戊二烯。它们包含一个或两个有机元素基团。-戊二烯基锂(2)仅与Cl-SPh,Br-SePh,Cl-PPh 2和Cl-AsPh 2(元素上的孤对)反应生成相应的E-1-(有机元素)-2,4-戊二烯,而对于Cl-MMe 3(M = Si,Ge,Sn)(2,3,4),Cl-GePh 3和Cl-SnPh 3(在元素上没有孤对),E-和Z-的混合物形成1-(有机元素)-2,4-戊二烯。给出了这种不同行为的解释。
