title: Cobalt PNC(NHC) 'pincers': ligand dearomatisation, formation of dinuclear and N2 complexes and promotion of C-H activation.
abstract: Studies of ligand dearomatisation in cobalt phosphino-picoline N-heterocyclic carbene (PNC(NHC))-type pincers have revealed the formation of dinuclear cobalt complexes by either side-arm metalation or C-H activation at the NHC backbone; in the latter case, the product complex, featuring an 'anionic dicarbene', originated from a dearomatised Co(I)-N2 complex.
