Abstract

Carbonylation of the strongly activated hafnocene dinitrogen complex, [{(Î·⁵-C₅H₂-1,2,4-Me ₃)₂Hf}₂(μ₂, Î·²,Î·²-N₂)], in the presence of electron-rich 4-substituted pyridines resulted in isolation of rare μ-nitrido hafnocene complexes prepared from N₂ cleavage. The electronic and molecular structures as well as the intermediacy in N-C bond forming reactions has been determined.
