IN A PROCESS FOR PRODUCING TRANSITION METAL CARBONYLS, SAID TRANSITION METAL BEING SELECTED FROM THE METALS OF GROUPS VB, VIB, VIIB, AND VIII OF THE PERIODIC TABLE, THE STEP WHICH COMPRISES CONTACTING AT A TEMPERATURE BETWEEN ABOUT -25* C. AND ABOUT 175* C. THE FOLLOWING: (1) AN ANHYDROUS TRANSITION METAL HALIDE SELECTED FROM THE GROUP CONSISTING OF CHLORIDE, BROMIDE AND IODIDE, (2) AN ALKALI METAL, (3) FROM ABOUT ONE TO ABOUT 100 MOLE PER CENT BASED ON SAID ALKALI METAL OF AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF POLYPHENYLS, ALKYL-SUBSTITUTED POLYPHENYLS, ARYL-SUBSTITUTED POLYPHENYLS, NAPHTHALENE, ALKYL-SUBSTITUTED NAPHTHALENES, AND ARYL-SUBSTITUTED NAPHTHALENES, (4) A LIQUID ORGANIC SOLVENT SELECTED FROM THE GROUP CONSITING OF CYCLIC ALIPHATIC ETHERS HAVING NOT MORE THAN ABOUT 4 CARBON ATOMS PER OXYGEN ATOM AND NON-CYCLIC ALIPHATIC EHTERS WHICH CONTAIN A METHOXY GROUP AND WHICH HAVE NOT MORE THAN ABOUT 4 CARBON ATOMS PER OXYGEN ATOM, AND (5) CARBON MONOXIDE GAS UNDER PRESURE.
