The regiodivergent hydrosilylation of alkenes is reported using two bisiminopyridine cobalt(II) catalysts. Variation of pre-catalyst activator and ligand substituents were investigated to enable the controlled, regiodivergent hydrosilylation of both aryl- and alkyl-substituted alkenes with phenylsilane. In contrast to other regiodivergence strategies, excellent regioselectivity for either isomer was achieved using the same ligand class but differing by a single methyl group (ethyl vs. isopropyl).

钴催化、配体控制的区域发散烯烃氢化硅烷化

使用两种双亚胺吡啶钴 (II) 催化剂报道了烯烃的区域发散氢化硅烷化。研究了催化剂前活化剂和配体取代基的变化，以实现芳基和烷基取代的烯烃与苯基硅烷的受控、区域发散的氢化硅烷化。相对于其他regiodivergence策略，为任一异构体的区域选择性优良使用相同的配位体类，但由单一的甲基（乙基对不同达到异丙基）。
