Microwave-Assisted Heterogeneous Transfer Hydrogenation of Ketones

Article Preview

Abstract:

A first and efficient procedure has been developed for microwave-assisted transfer hydrogenation of ketones. Silica gel-supported ligand 2 has been prepared for the transfer hydrogenation. This immobilized ligand-Ru complex acted as an efficient catalyst for the hydrogen transfer reaction of ketones. The MW-assisted reactions using the supported ligand 2 could reach completion within 20~40 min.
