Motivated by our preliminary results on Cp2TiF2-catalysed 1,4-hydrosilylation of monosubstituted dienes, we assessed the performance of several titanium complexes for the hydrosilylation of 2,3-dimethylbutadiene, a representative bulky diene. An open-bent titanocene complex [Me2C(C5H4)2TiMe2] performed the best and proved to be efficient for the hydrosilylation of a variety of substrates such as disubstituted dienes, activated alkenes, and even an acetylene.
受我们初步关于Cp2TiF2催化单取代二烯的1,4-氢硅烷化反应结果的启发,我们评估了几种钛络合物在代表性的大位阻二烯2,3-二甲基丁二烯的氢硅烷化反应中的性能。开弯型二茂铁钛络合物[Me2C(C5H4)2TiMe2]表现最佳,并证明对各种底物如二取代二烯、活化烯烃甚至乙炔的氢硅烷化反应都有效。
