We report the imido group exchange transformation upon reactions with nitriles with the formation of a new vinylimido group from the incoming nitrile and a free nitrile from the initial imido group. Preliminary studies suggest the mechanism comprises elimination of triethylamine from the amminium group as the initial step, followed by the deprotonation of the incoming nitrile, followed by the rearrangement of its carbanion into an imido group at the tantalum center. The cationic group on the imido ligand can be replaced with another neutral nucleophile, which was demonstrated by NEt3to PPh3and NEt3to DMAP exchange reactions.
