The photochemical hydroformylation of 1-octene with cobalt/phosphane complexes in methanol leads under mild conditions (80 deg C, 80 bar CO/H2) with >= 90percent selectivity to linear aldehydes.The reaction rate increases with temperature (Ea = 5 - 6 kcal/mol) and synthesis gas pressure, and is nearly independent of the cobalt source, e.g.Co(OAc)2, Co2(CO)8, or Co2(CO)6(PBu3)2.At low pressures hydroesterification is the preferred photoreaction of 1-octene.Isoprene reacts under similar conditions to give unsaturated oxoproducts and linear isoprene dimers.With unmodified octacarbonyldicobalt the hydroformylation of internal olefins is enhanced by UV light, but not the reaction of terminal olefins or dienes.UV irradiation of cobalt acetate under hydroformylation conditions leads to rapid reduction of the Co(II) species, thus decreasing the induction period from ca. 15 h (without irradiation) to ca. 30 min.
