asymmetric reduction of alkyl phenyl, dialkyl and alkyl cyclohexyl ketones has been achieved via hydrosilylation, catalyzed by a rhodium(I) complex with optically active phosphine ligands using various hydrosilanes. A mechanism of the induction of asymmetry is proposed in view of the stereochemical course of the reaction.
通过使用各种氢化硅烷与具有光学活性膦配体的铑(I)配合物催化的氢化硅烷化反应,已实现了烷基苯基,二烷基和烷基环己基酮的有效不对称还原。考虑到反应的立体化学过程,提出了一种引起不对称的机理。
