The hydroformylation of formaldehyde to glycol aldehyde (OHCCH2OH) catalysed by rhodium complexes has been studied.The hydrogenation product, methanol, is also formed.The ratio of hydroformylation to hydrogenation is very dependent on the solvent.Hydroformylation is favoured only in N,N-disubstituted amides, with methanol formation predominating in other solvents.This is attributed to the electronic effect of coordinated amide.Complexes of the type RhCl(CO)L2, (L=PPh3, P(p-tol)3, P(m-tol)3 (tol=tolyl) P(p-FC6H4)3 radical) are most efficient as catalysts.Deuteration studies show that the mechanism is analogous to that of alkene hydroformylation.A detailed reaction mechanism is proposed.
