Piano-stool N-heterocyclic carbene iron complexes: Synthesis, reactivity and catalytic applications [PDF]
Coordination Chemistry Reviews, 2017 Abstract This review summarises the advances of N-heterocyclic carbenes (NHCs) as ligands to iron half-sandwich complexes, often referred to as piano-stool complexes because of their structural motif. The review introduces various synthetic routes towards this sub-class of NHC iron-complexes including in particular direct and transmetallation ...
