of protocols describing specific monosubstituted silsesquioxanes is limited. There are even fewer reports on alkynyl and/or germyl functionalities appearing together with the POSS compounds. Here, a series of novel kinds of cubic monosubstituted POSS bearing alkynyl and germyl functionality in one molecule are reported. These compounds were synthesized by effective germylative coupling of terminal alkynes
尽管在庞大的倍半
硅氧烷(POSS)家族中有多种功能化合物,但描述特定单取代倍半
硅氧烷的方案数量有限。关于炔基和/或胚芽官能度与POSS化合物一起出现的报道甚至更少。在此,报道了一系列在一个分子中带有炔基和芽基官能团的新型立方单取代的POSS。这些化合物是通过在Ru–H络合物存在下,末端
炔烃与
乙烯基锗烷进行有效的萌芽偶联而合成的。确定了产品的结构。此外,还进行了具有Ru-Ge的配合物的
化学计量反应,以提出该反应的一般机理。
