Résumé

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.
