Direct catalytic transformation of chlorosilanes into organosilicon compounds remains challenging due to difficulty in cleaving the strong Si–Cl bond(s). We herein report the palladium-catalyzed cross-coupling reaction of chlorosilanes with organoaluminum reagents. A combination of [Pd(C3H5)Cl]2 and DavePhos ligand catalyzed the selective methylation of various dichlorosilanes 1, trichlorosilanes 5
由于难以裂解牢固的Si-Cl键,氯硅烷直接催化转化为有机硅化合物仍然具有挑战性。我们在本文中报道了氯硅烷与有机铝试剂的钯催化交叉偶联反应。[Pd(C 3 H 5)Cl] 2和DavePhos配体的组合催化了各种二氯硅烷1,三氯硅烷5和四氯硅烷6的选择性甲基化,得到了相应的一氯硅烷。
