The mass spectra of the following fluorocarbon derivatives of transition metals have been investigated: (a) the perfluoroalkyl derivatives RfMo (CO)3C5H5 ( Rf = CF3 and C3F7); (b) the perfluoroacyl derivatives CF3COM(CO)3C6H5 (M = Mo and W), C3F7COM(CO)3C5H5 (M = Mo and W), and C3F7COFe(CO)2C6H6; (c) the perfluoraryl derivatives RfFe(CO)2C5H5 ( Rf/ = C6F5, p-HC6F4, 3, 4-H2C6F3, and p-CF3C6F4); (d) the hexafluorobutyne derivatives [(CF3)2C]3 MNCCH3 (M = Mo and W); and (e) the bis (trifluoromethyl)tetramethylbicyclo-[2.2,2] octatriene complexes C14H14F6Fe (CO)3 and C5H5CoC14H14F6. Unusual features observed in these mass spectra include the following: (a) Evidence for elimination of the neutral metal fluoride fragments FeF2 and C5H5CoF; (b) evidence for the elimination of neutral HF and CF2 fragments; (c) evidence for the elimination of a bridge in the bicyclo [2,2,2] octatriene derivatives; (d) decarbonylation of RfCOMo (CO)3C5H5 compounds, but not their tungsten analogs, in the mass spectrometer; and (e) evidence for the eliminations of C4F4 and CH3CN fragments in the mass spectra of the [(CF3)2C2]3MNCCH3 complexes.

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.
