摘要：

Carbonylrhodium complexes formed during hydroformylation of CH2O from various rhodium precursors were investigated by in situ IR spectroscopy. It was found that under the conditions of the hydroformylation of CH2O in N,N-dimethylacetamide (DMAA), RhH(CO)(PPh(3))(3), RhCl(CO)(PPh(3))(2), RhCl(PPh(3))(3), RhCl(CO)(PBu(3))(2), and [RhCl(CO)(2)](2) form complex systems that necessarily contain anionic complexes, [Rh(CO)(2)L(x)(DMAA)(y)](-) (L = PPh(3), PBu(3), x = 1 to 2, y = 1 to 0; [Rh(CO)(4)](-)). The participation of ionic structures in the hydroformylation of CH2O, most likely, in the step of the activation of CH2O, was proven by kinetic techniques.
