摘要：

Reaction of carbon monoxide with biscyclopentadienyl-methyl- or -benzyl-vanadium(III) gave carbonylbiscyclopentadienylacylvanadium(III), while under the same conditions biscyclopentadienylphenylvanadium(III) yielded dicarbonyl (phenyl-η⁴-cyclopentadiene)(η⁵-cyclopentadienyl)vanadium(I) which forms carbonyl(cyclopentadienyl)(phenylcyclopentadienyl)vanadium(II)via phenyl migration to a cyclopentadienyl ligand.
