Reaction of ammonium thiocyanate with dihalocarbonyls of molybdenum and tungsten(11) leads to the elimination of ammonium chloride and the formation of a dithiocyanatocarbonyl complex of the transition metal. Although the thiocyanatocarbonyls themselves have not been isolated in a pure state, a number of substituted derivatives with phosphorus donor ligands have been prepared and characterized. In general these complexes are less stable than the corresponding carbonyl halide derivatives.

An efficient synthesis of diarylallenylidene pentacarbonyl chromium and tungsten com­plexes is presented. Irradiation of M(CO)6 in THF affords (CO)sM[THF], Substitution of the THF ligand by diarylpropargylalcoholate and subsequent desoxygenation with COCF gives the title compounds in good yield. (The structure of diphenylallenylidene pentacarbonyl chromium has been determined by X-ray structure analysis
