Heating NdI2 (1) or DyI2 (2) with vanadocene (3) in benzene at 85°C led to the formation of bis(benzene)vanadium in 10 and 24 % yields, respectively. The lanthanide products were isolated in the form of CpLnI2(THF)3 after crystallization from THF. The interaction of 2 with 3 in isopropylbenzene at 90°C yielded a mixture of (arene)2V complexes from which a small amount of bis(isopropylbenzene)vanadium was isolated. The same reaction did not occur in mesitylene. From the reaction of 2 with 3 in molten naphthalene at 100°C, the heterobimetallic cluster {[CpDy(μ-I}2]7Cp 2V(μ-I)}(4) was isolated in low yield. The reaction of Cp 2Cr with 1 or 2 in benzene at ambient temperature afforded the dimer [CpCr(μ-I)]2 (5) and a dysprosium complex, Cp2DyI (6) (in the reaction with 2). When the reaction with 2 was carried out at 80°C, along with compound 6, the -ate complex {[Cp2DyI2] -[Cp2Cr]+}(7) was crystallized from the reaction solution. Nickelocene was reduced by 2 in benzene at 80°C to nickel metal. The dysprosium product was isolated as solvent-free complex 6. Ferrocene and cobaltocene did not react with 1 and 2 in benzene. The molecular structures of compounds 4, 5, and 7 were characterized by X-ray diffraction analysis. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
