ABSTRACT:
Novel heterogeneous catalysts consist essentially of an anion exchange resin to which is bound ionically an anionic metal carbonyl species having the general formula M.sub.n (CO).sub.m (X).sub.p.sup.z- where M is a transition metal such as for example rhodium, cobalt, ruthenium, osmium, iridium, or iron; X is an anion, for example halide, hydride, or alkyl; n ranges from 1 to 12; m ranges from 1 to 34; p ranges from 0 to 2n+1; and z is an integer charge ranging from 1 to 5. The catalyst in which M is rhodium, m=2, p=2, n=1, and z=1 is highly effective for the carbonylation of alcohols to acids and esters. Many of these anionic species have utility in the hydroformylation of olefins.
