BARICELLI, P.J. et al. HOMOGENEOUS CATALYSIS REACTION OF FORMALDEHYDE WITH SYNTHESIS GAS USING RHODIUM COMPLEXES. Bol. Soc. Chil. Quím. [online]. 2000, vol.45, n.3, pp. 385-389. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442000000300008.

In the present work, we report the homogeneous catalytic hydroformylation reaction of formaldehyde with rhodium complexes like [Rh(CO)₂L₂](PF₆) with L = pyridine (1) or 4-picoline (2), using different solvents such as toluene, acetone, N,N-dimethylformamide, and 4-picoline. The experiments were carried out in an autoclave (Parr, 100 mL), 10 atm, CO/H₂ = 1 and ratio catalyst/substrate 1/100. Preliminary kinetics parameters show a high catalytic activity of these complexes to the formation of methanol and methyl formate
