The scandium dihydrosilyl complexes Cp*(2)ScSiH(2)R (R = Mes (4), Trip (5), SiPh(3) (6), Si(SiMe(3))(3) (7); Mes = 2,4,6-Me(3)C(6)H(2), Trip = 2,4,6-(i)()Pr(3)C(6)H(2)) and Cp*(2)ScSiH(SiMe(3))(2) (8) were synthesized by addition of the appropriate hydrosilane to Cp*(2)ScMe (1). Studies of these complexes in the context of hydrocarbon activation led to discovery of catalytic processes for the dehydrogenative
钪二氢甲硅烷基配合物 Cp*(2)ScSiH(2)R (R = Mes (4), Trip (5), SiPh(3) (6), Si(SiMe(3))(3) (7); Mes = 2,4,6-Me(3)C(6)H(2), Trip = 2,4,6-(i)()Pr(3)C(6)H(2)) 和 Cp*( 2)ScSiH(SiMe(3))(2) (8) 是通过向 Cp*(2)ScMe (1) 添加适当的氢硅烷来合成的。在碳氢化合物活化的背景下对这些复合物的研究导致发现了通过 sigma-bond 复分解用 Ph(2)SiH(2) 对碳氢化合物(包括甲烷、异丁烯和环丙烷)进行脱氢硅烷化的催化过程。
