A highly stereoselective hydrosilylation of unsymmetrical vicinal diketones with PhSiH3 was accomplished under the frustrated Lewis pair (FLP) catalysis, delivering 1,2-di-aryl-1,2-anti-diols in high yields with >99/1 dr values and up to 97 % ee. The chiral FLP catalyst exhibits the ability to control regio-, diastereo-, and enantioselectivities, while silane PhSiH3 facilitates an intramolecular hydrosilylation
在受阻路易斯对 (FLP) 催化下,用 PhSiH 3实现不对称邻位二酮的高度立体选择性氢化硅烷化,以高产率生成 1,2-二芳基-1,2-抗二醇,dr 值 >99/1高达 97% ee 。手性FLP催化剂表现出控制区域选择性、非对映选择性和对映选择性的能力,而硅烷PhSiH 3促进第二个羰基的分子内氢化硅烷化。
