Carboxylic acids, however, are difficult to hydrogenate in comparison with ketones and esters. Ligand protonation and resultant ligand dissociation, combined with overcoordination of the generated vacant sites at the metal center by the (bidentate) carboxylate conjugated base, result in detrimental catalyst deactivation. These pathways are especially problematic with first-row transition metals, which typically have weaker metal-ligand bonds than their second- and third-row congeners. 感觉两句话自己都矛盾的。 |
