Abstract
Arene-immobilized Ru(II)TsDPEN Noyori-Ikariya catalysts anchored to silica through the coordinated η6-arene are provided. The catalysts efficiently catalyze many reactions, including the asymmetric transfer hydrogenation of ketones to alcohols.
Claims5
A method of catalyzing asymmetric hydrogenation of a ketone, comprising
- contacting the ketone with a hydrogen donor in the presence of the arene-Ru (II) catalyst having the formula
- wherein X is a halogen or CN,
- Y and Z are the same or different and each is a carbon ring structure:
- L is a carbon linker;
- and
- ◯ is a silica support.
