| Abstract: | Formic acid was synthesized in a high yield at room temperature in the presence of the Wilkinson complex and an excess of PPh3. The catalytic properties of the rhodium complex depend strongly on the reaction conditions. The mechanism of the rhodium catalyst deactivation was studied by the kinetic method and 31P NMR spectroscopy. The methods for the stabilization of the rhodium catalyst were found. |
