可以通过最近报道的称为炔烃与乙烯基硅化合物的甲硅烷基化偶联的催化方法,有效地合成已知为潜在的有机金属试剂和光电子材料前体的甲硅烷基甲基萘。[RuHCl(CO)(PR 3)n ](R = i Pr,Cy,Ph; n = 2–3)在最佳条件下有选择地产生各自的甲硅烷基锗。乙炔基锗烷与二乙烯基硅衍生物(如硅氧烷,硅氮烷,双(甲硅烷基)苯和双(甲硅烷基)乙烷)的甲硅烷基化可得到高收率和高选择性的单乙炔基锗烷基取代的乙烯基二硅产品,但伴有痕量的二炔基锗烷基衍生物。所有催化结果以及将乙炔基锗烷插入Ru-Si键的化学计量研究都提出了研究反应机理的方案。
reaction opens the first transition metal catalytic route for the preparation of this class of organogermanes, which are useful reagents for organic synthesis. The mechanism elucidated by NMR spectroscopic study of stoichiometric reactions shows that this process is a new catalytic activation of an sp-hybridized C−H bond involving the previously discovered activation of the C−Ge bond.
