PREPARATION OF ACYL(CARBOXYLATO)NICKAL AND -PALLADIUM COMPLEXES M(COR) (OCOR')L2 (M = Ni, Pd) AND REVERSIBLE REDUCTIVE ELIMINATION OF CARBOXYLIC ANHYDRIDES, RCOOCOR'

Article abstract of DOI:10.1246/cl.1981.193

Acyl(carboxylato)nickel(II) and -palladium(II) complexes, M(COR) (OCOR')L2 2 are prepared by 1:1 reactions of MR(OCOR')L2 1 with CO at -78 deg C, whereas similar reactions in the presence of excess CO at room temperature afford the reductive elimination products, RCOOCOR'.Acid anhydrides add oxidatively to an Ni())-complex to afford a complex of the type 2.
