This paper describes catalytic activation studies of the water–gas shift reaction by cis-[Rh(CO)2(amine)2]PF6 (amine = 4-picoline, 3-picoline, 2-picoline, pyridine, or 2,6-lutidine) heterogenised on poly(4-vinylpyridine) in aqueous 2-ethoxyethanol. The effect of varying the nature of the amine was investigated. The rhodium complexes bearing 4-picoline (4-pic) ligands proved to be most active among those surveyed, and displaying turnover frequencies for hydrogen production of 8.9 mol of H2 per mole of Rh per day for 9.4x10-5 mol cis-[Rh(CO)2(4-pic)2]PF6/1.00 g poly(4-vinylpyridine), P(CO) = 0.9 atm at 100°C.
