activation of ene diamido samarium methoxide with hydrosilane for selectively catalytic hydrosilylation of alkenes and Polymerization of styrene an experimental and theoretical mechanistic study
Inorganic Chemistry, 2016Co-Authors: Chaoyue Zhao, Jinxi Liu, Hanmin Huang, Fengxin Wang, Chunming CuiAbstract:Samarium methoxide incorporating the ene-diamido ligand L(DME)Sm(μ-OMe)2Sm(DME)L (1; L = [DipNC(Me)C(Me)NDip]2–, Dip = 2,6-iPr2C6H3, and DME = 1,2-dimethoxyethane) has been prepared and structurally characterized. Complex 1 catalyzed the Syndiospecific Polymerization of styrene upon activation with phenylsilane and regioselective hydrosilylation of styrenes and nonactivated terminal alkenes. Unprecedented regioselectivity (>99.0%) for both types of alkenes has been achieved with the formation of Markovnikov and anti-Markovnikov products in high yields, respectively, whereas the Polymerization of styrene resulted in the formation of syndiotactic silyl-capped oligostyrenes. The kinetic experiments and density functional theory calculations strongly support a samarium hydride intermediate generated by σ-bond metathesis of the Sm–OMe bond in 1 with PhSiH3. In addition, the observed regioselectvity for hydrosilylation and Polymerization is consistent with the calculated energy profiles, which suggests that the...
