respectively. Reaction of 1 with n-BuLi results in addition of n-Bu− to the terminal nitrogen of 1 to generate a hydrazonyl anion that reacts with 3 to afford the hydrazonyl complex (dtbpe)Cu−N(n-Bu)N═CH(dmp) (7) in 75% yield. Complexes 5−7 have been characterized by spectroscopic (NMR, IR) and X-ray diffraction methods.
