CARBONYL HALIDES GROUP 6 TRANSITION METALS .11. DITHIOCYANATOCARBONYL DERIVATIVES OF MOLYBDENUM AND TUNGSTEN(2)

Reaction of ammonium thiocyanate with dihalocarbonyls of molybdenum and tungsten(II) 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. © 1968 CSIRO. All rights reserved.
