Electrochemical reduction of vanadium salts under carbon monoxide. Synthesis of tetrabutylammonium hexacarbonylvanadate(–L)

Abstract

Vanadium(III) complexes can be carbonylated by electrochemical reduction in anhydrous solvents saturated with CO at low and medium pressures. With V(acac)₃ as substrate, tetrabutylammonium hexacarbonylvanadate(–L) is obtained in pyridine, with conversion yields of up to 82%. A simplified process to obtain hexacarbonylvanadium is described.
