摘要：
The color change from yellow to violet allows the formation of the intermediate [Cp2Ti(SiHMePh)-(pyridine)] to be monitored in the reaction of PhMeSiH2 with a pyridine in the presence of the precatalyst [Cp2TiMe2] [Eq. (a)]; the hydride [Cp2TiH] 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 [Cp2TiMe2]. R = Me, CO2Et.
