摘要:
The H-2 hydrogenations of PhN=CHPh and PhCH2N=CHPh 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)(2)NH, forms a labile N-bonded species that does not poison the catalyst system.
