additional donor group affords stable five-membered metal carbene chelates. Olefin-chelated metallacycles are obtained via aminolysis of alkoxy carbene complexes using allylamine. Heteroatom metal carbene chelates are accessible from ortho-lithiated methoxyarenes in a two-step process involving a sequential nucleophile/electrophile addition to metal carbonyls followed by thermal decarbonylation. Both
