A total loss of innocence: double ortho-metallation of bis(triphenylphosphano)iminium cation, [N(PPh(3))(2)](+), by tris(eta-naphthalene)tantalate(1-).
For the first time [N(PPh(3))(2)](+), or [PPN](+), has been shown to undergo an irreversible reaction with a transition metal complex under ambient conditions and affords a product containing a unique structural motif in which two phenyl groups on one PPh(3) substituent of [PPN](+) are ortho-metallated, while the third phenyl ring is hydrogenated to provide a tantalum bound 1,3-cyclohexadiene group.
