allows the formation of the intermediate [Cp2 Ti(SiHMePh)(pyridine)] to be monitored in the reaction of PhMeSiH2 with a pyridine in the presence of the precatalyst [Cp2 TiMe2 ] [Eq. (a)]; the hydride [Cp2 TiH] is postulated to be the key intermediate in the catalytic cycle. The regioselective hydrosilylation of pyridine and also substituted pyridines can be catalyzed by the titanocene [Cp2 TiMe2 ]. R=Me
颜色从黄色变为紫色,可以在存在中间体P [Cp 2 TiMe 2 ] [Eq]的情况下,在PhMeSiH 2与吡啶的反应中监控中间体[Cp 2 Ti(SiHMePh)(吡啶)]的形成。。(一种)]; 氢化物[Cp 2 TiH]被认为是催化循环中的关键中间体。吡啶和取代的吡啶的区域选择性氢化硅烷化可以被钛茂[Cp 2 TiMe 2 ]催化。R = Me,CO 2等。
