A total loss of innocence: double ortho-metallation of bis(triphenylphosphano)iminium cation, [N(PPh3)2]+, by tris(η-naphthalene)tantalate(1−)†‡
Abstract
For the first time [N(PPh3)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 onePPh3 substituent of [PPN]+ are ortho-metallated, while the third
