A non-innocent, π-extended N-heterobicyclic carbene–thiolate ligand†
Abstract
A bidentate NHC–thiolate ligand based on the imidazo[1,5-a]pyridine scaffold and featuring an extended π-system is described. It is derived from a readily available zwitterionic precursor and the chemistry of the corresponding homoleptic Ni(II) complex is investigated.
