Transition Metal Carbonyl Compounds

Abstract

Chapter 3, “Transition Metal Carbonyl Compounds,” focuses on complexes of transition metals that involve at least one carbonyl ligand. Included here are syntheses of the homoleptic compounds [Et4N][V(CO)6],V(CO)6, and Ru3(CO)12, as well as for several compounds of primary interest as synthetic intermediates, such as the neutral M(0) compounds Mo(CO)3(py)3 and W(CO)4(dppe) and salts of the anionic M(I) complexes [Rh(CO)2Cl2]− and [Ir(CO)2I2]−. Also represented are procedures that illustrate the formation of carbonyl ligands from the reaction solvent, e.g., DMF, as for the useful intermediate [PPN][Ru(CO)2Cl3(DMF)]. Further compounds derived from these intermediates include a Mo(II) allyl complex, TpMo(CO)2(η3-CH2CHCHCO2CH3), a W(0) fullerene-60 derivative, W(CO)3(dppe)(C60), a CVD precursor, Ru(CO)2(hfac)2, a thiolate-bridged dimer, {Ir(μ-StBu)(CO)2}2, and a water-soluble Rh(I) phosphine complex, Na6[Rh(CO)Cl{PC6H4SO3}2].
