activity and stereoselectivity of phosphane- and N-heterocyclic carbene (NHC)-containing ruthenium benzylidene complexes have been evaluated in macrocyclic ring-closing olefin metathesis to produce unsaturated lactones and lactams. The success of the macrocyclization depends on the nature of the ligand (phosphane or N-heterocyclic carbene) on the ruthenium center and on the NHC properties. As for stereoselectivity
