AbstractThe effect of metal complex on hydrogenation of o-chloronitrobenzene (CNB) over poly-vinylpyrrolidone-stabilized platinum clusters (PVP-PO has been studied in methanol at 303 K and atmospheric pressure. The addition of metal complexes to the catalytic system can considerably modulate both the activity and the selectivity of the catalyst. A low activity (0.41 mol H-2/mol Pt s) and low selectivity (42.6%) were obtained when the neat PVP-Pt colloidal clusters were used as a catalyst. Upon the addition of the complexes Ni(AcAc)(2) and Na[Co(AcAc)(3)], the better selectivity to o-chloroaniline to-CAN) were promoted to 76.2% and 76.5%, and the higher activities (0.72 mol H-2/mol Pt s and 0.83 mol H-2/mol Pt s) were obtained, respectively. On the other hand, when the complex Ni(en)(3)Cl-2 was introduced as a modifier, the highest selectivity to o-CAN (94.0%) was achieved, though the activity was lowered to 0.16 mol H-2/mol Pt s.
