THE SYNTHESIS AND ACTIVITY OF SILICONE SUPPORTED TRANSITION METAL COMPLEX CATALYSTS Ⅵ Hydrogenation of Aromatic Nitrocompounds in the Presence of Poly-γ-(m-diphenylphosphinophenyl) propylsiloxane—Palladium Complex as Catalyst[J]. 1983,(1):35-41.DOI:
Palladium complex of silicon-supported Poly-γ-(m-diphenylphosphinophenyl) propylsiloxane has been found to catalyze the selective hydrogenation of some aromatic nitrocompounds to corresponding aromatic amines at 40℃ under an atmospheric hydrogen pressure. Protonic solvents, such as, i-propanol, 95% ethanol, remarkably promoted the activity of the palladium complex, but aprotic solvent benzene was of retardative effect. The catalyst could be recovered and reused without any appreciable loss of catalytic activity as shown in the previous papers about the hydrogenation of olefins.
