Reactions of alkali-metal naphthalenides with VCl3(THF)3, CrCl3(THF)3, MoCl3(THF)3, and MoCl4(THF)2 in THF provided up to 29%, 24%, 20%, and 17% yields of the respective bis(naphthalene)metal(0) complexes. These highly reactive "naked" early-transition-metal atom reagents were accessible previously as pure substances only from metal atom reactions carried out in specialized apparatus available to few chemists. The nature of bis(naphthalene)vanadium(0) has been confirmed by a single-crystal X-ray structural characterization. These results provide another indication that the arene radical anion route is an important general strategy for the synthesis of homoleptic transition-metal arene complexes.
