WebFeb 15, 2003 · The H2 hydrogenations of PhNCHPh and PhCH2NCHPh are catalyzed by the precursor [Rh(COD)(PPh3)2]PF6. However, the amine product PhNHCH2Ph poisons the catalyst by coordination to the Rh through an arene moiety, while the other amine product, (PhCH2)2NH, forms a labile N-bonded species that does not poison the catalyst system.
