Homogeneous catalytic hydrogenation of unsaturated aldehydes to form saturated aldehydes
Abstract
The homogeneous catalytic hydrogenation system for olefins based on the use of tris(triphenylphosphine)chlororhodium has been extended to the specific reduction of the unsaturated carbon–carbon bond in propenal, but-2-enal, and trans-2-methylpent-2-enal, resulting in the corresponding saturated aldehydes. The method would appear to be of general utility for such reductions.
