ResumoThe homogeneous hydrogenation of PhCCH catalyzed by RhClL3, Rh(COD)L2+, and Rh(COD)dppe+ (L PPh3; COD1,5-cyclooctadiene; dppe = 1,2-bis(diphenylphosphino)ethane) has been investigated using para-hydrogen-induced polarization (PHIP) which allows that in accord with earlier studies, for RHClL3 the addition of H2 is reversible, whereas for Rh(CO)(dppe)+ and Rh(COD)L2+, H2 addition in hydrogenation catalysis is irreversible.
