ermane) or chloroalkyldigermanes (1,2-dichlorotetraethyl- or 1,2-dichlorotetramethyldigermane) with allylic chlorides proceeds smoothly even at room temperature in the presence of tris(dibenzylideneacetone)dipalladium(0) to afford the corresponding 2-alkenylgermanes in good to high yields.
即使在室温下,苯基烷基二硬脂酸酯(1,2-二苯基四乙基-,1,2-二苯基四甲基-,苯基五乙基-或苯基五甲基二甲基硬脂酸酯)或氯烷基二茂金属(1,2-二氯四乙基-或1,2-二氯四甲基硬脂酸酯)的复分解反应即使在室温下在室温下也能顺利进行。存在三(二亚苄基丙酮)二钯(0),以高至高收率得到相应的2-烯基锗烷。
