Successive treatment of triallylamine with zirconocene chloride hydride and germanium tetrachloride affords 1-aza-5-germa-5-chlorobicyclo[3.3.3]undecane, which is converted to the 5-organo derivatives by the reaction with Grignard or lithium reagents. The organo groups showed higher reactivities toward Stille-type coupling than the corresponding organotributylgermanes.
用氢化锆氧化锆和四氯化锗连续处理三烯丙基胺,得到1-氮杂5-锗5-氯双环[3.3.3]十一烷,通过与格氏试剂或锂试剂反应转化为5-有机衍生物。有机基团显示出比对应的有机三丁基锗烷更高的对Stille型偶联的反应性。
