Abstract

Homogeneous catalytic reduction of nitrobenzene to aniline by cis-[1r(CO) 2(amine) 2]PF 6 (amine = 4-picoline, 3-picoline, 2-picoline, pyridine, pyridine, 3,5-lutidine or 2,6-lutidine) in aqueous amine 2/8, v/v, P(CO) = 0.9 atm, T = 100°C, [Ir] = 10 mM and substrate/lr = 2500 under water gas shift reaction conditions is described. Additionally the effect of various amines as additives was examined.
