Polyketones are obtained by the copolymerization of carbon monoxide and ethylene in the presence of a palladium catalyst formed in situ from Pd(OAc) 2 , dppp and formic acid in methanol which acted as a solvent. The productivity (g polymer/g Pd * h) is significantly influenced by the concentration of formic acid. Using the ratio Pd/dppp/HCOOH = 1/1/3000 at 90 • C and 45 atm, a productivity of 7500 h −1 is obtained. It is suggested that the efficiency of HCOOH as a promoter is due to its capability to act as a source of Pd-hydride species, which initiates the catalytic cycle.

Various available approaches for catalytic carbonylation reactions using formates and formamides with transition metal catalysts are reviewed. Pd complexes catalyze the hydroesterification or hydrocarbamoylation of alkynes using aryl formates or formamides, respectively, as the carbonyl sources. The esterification of aryl halides with aryl formates proceeds in the presence of a Pd catalyst with suitable ligands. Using a Cu complex with a bulky bidentate phosphine ligand is used as a catalyst, boraformylation and silaformylation of allenes efficiently proceeds using alkyl formates as a formyl source.
