Efficient hydroformylation rhodium catalysts using water as solvent and hydrogen source
Abstract
The fast and selective conversion of alkenes into aldehydes can be achieved under mild conditions by using the CO/H2O couple in the presence of the water-soluble complexes Rh2(µ-SBut)2(CO)2(Ls)2, Rh(cod)(Ls)2+(cod = cyclo-octa-1,5-diene), and RhH(CO)(Ls)3, where Ls is the trisulphonated phosphine, P(m-C6H4SO3Na).
