Formyl fluoride reacts with metal carbonyl anions in a manner similar to acetic formic anhydride.Although formyl complexes may have been formed as unstable intermediates, no neutral formyl complexes could be isolated but rather the expected decomposition products, the metal carbonyl hydrides or dimers, were produced.The attempted oxidative addition of formyl fluoride to various coordinately unsaturated metal complexes also did not result in the formation of formyl derivatives.HF adducts were obtained from the reaction of Ir(CO)Cl(PR3)2 or M(PPh3)4 (M=Pt or Pd) with formyl fluoride whereas Ru(NO)Cl(PPh3)2 and Rh(PPh3)3Cl give the CO complexes Ru(NO)(CO)Cl(PPh3)2 and Rh(CO)Cl(PPh3)2, respectively.
