Chelate complexes of the type [ Rh( q2-0,Z) (PR,),] (Z = CCH,, CCF3, CtBu, S( 0) -p-C&I&H,; PR, = PiPr,, PPhiPr,, PPh,iPr) catalyze the hydrogenation of phenylacetylene in toluene solution at 60°C. Selectivities close to 100% are achieved for the hydrogenation of the alkyne to the alkene in the pre
