This review is a critical presentation of catalysts based on palladium and ruthenium bearing N-heterocyclic carbene ligands that have enabled a more sustainable approach to catalysis and to catalyst uses. Aspects of sustainability associated with these in terms of catalytic uses or synthetic access are reviewed.
