Abstract: Metal carbonyl complexes of the formula (L)xM(CO)n-(1+XD)(COR)(CH3) in which x is 0 or 1, L denotes a unidentate to tridentate ligand, M is a metal atom of the Groups VA, VIA, VIIA and VIII, n is 4, 5 or 6, D is the number of CO ligands replaced by L and R is an aryl, alkyl or aralkyl radical are disclosed. These complexes are made by reacting the metal carbonyl or L-substituted derivative thereof with an organo-alkali metal compound in an organic solvent and inert atmosphere to form an intermediate of composition B[LxM(CO)n-(1+XD)COR] in which B is an alkali metal atom. The alkali metal atom is then eliminated by acidification and the complex is formed by reaction with an alkylating agent, e.g. dimethyl sulphate, diethyl sulphite or diazomethane. The intermediate can be, if desired, precipitated as a quaternary ammonium salt of formula in which R1 is an alkyl radical, e.g. methyl. The organic solvent can be ethers or hydrocarbons. The reaction temp. may be 0-100 DEG C. Acidification can be with a mineral acid, e.g. H2SO4 or HCl. The inert atmosphere can be N2 or a rare gas. Aldehydes, e.g. and benzaldehydes can be made by hydrolysis of the intermediate.
