Article abstract of DOI:10.1039/DT9900002551

Reduction of bis(arene)vanadium((0) complexes (1) with potassium in co-ordinating ether solvents gives solutions of the corresponding bis(arene)vanadate(-1) derivatives (2a; arene= benzene) and (2b; arene= mesitylene).Solvated potassium salts were isolated in yields depending on the arene ligands and the type of procedure required.The e.s.r. spectra of the reduction mixtures both in 1,2-dimethoxyethane and hexamethylphosphoramide are discussed.Solutuons of K (2a) in tetrahydrofuran are quickly reoxidized by both carbon mono- and di-oxide to give the vanadium(0) complex (1a); C1 and C2 products are formed, the relative yields depending on the concentrations of the reactants.
