An Efficient and Selective Monohydrido Rhodium(I) Homogeneous Hydrogenation Catalyst Containing a Cyclic Phosphine

Abstract

The preparation of the complex RhH(DBP)₄ (where DBP is a dibenzophosphole derivative) is described. It is a very effective and selective catalyst for the homogeneous hydrogenation of terminal olefins. Kinetic and mechanistic data for the hydrogenation of 1-hexene are presented.
