One reaction of this type reacts alpha, beta-unsaturated carbonyls with Hantzsch esters under amine catalysis. Discoverers of an asymmetric version of this reaction used in the industrial synthesis of L-DOPA from an achiral arene won part of the 2001 Nobel Prize in Chemistry. That asymmetric form of this reaction can be catalyzed by ruthenium-BINAP complexes developed by Noyori. A square-planar tris(triphenylphosphine) rhodium(I) complex was developed in 1966 to homogeneously catalyze this reaction; that is Wilkinson's catalyst. When this reaction is incomplete, it can result in cis-trans isomerization, and thus its "partial" form is responsible for the production of trans fats. For 10 points, name this reduction that involves reacting a substrate with the namesake light gas.
