Double deprotonation of coordinated ethylimide to CH3CN: molecular mechanism and relevance to the chemistry of Mo and W organoimides.
Reaction of [MCl(NEt)(dppe)2)Cl (M = Mo, W) with n-BuLi in tert-butyl methyl ether under an N2 atmosphere yields the M0 bis(dinitrogen) complexes [M(N2)2(dppe)2] and acetonitrile. A mechanism is proposed for this reaction which involves an anionic chloro-acetonitrile intermediate. The implications of these findings to the chemistry of Mo and W organoimides are discussed.
