A general synthesis of transition-metal carbene complexes: Cr0, Fe0, IrI, NiII, PdII, PtII, and AuI mono- and oligo-carbene species from electron-rich olefins
Abstract
A general method of synthesis of transition metal carbene complexes involves displacement of CO, olefin, tertiary phosphine, or hal– from a suitable metal precursor by a nucleophilic carbene fragment derived from an electron-rich olefin; the latter appear to be comparable in their transition metal reactivity to tertiary phosphines.
