The mass spectra of the following olefin derivatives of metal carbonyls have been investigated: (a) Arene—tungsten tricarbonyl complexes of toluene, p-xylene, and mesitylene; (b) The cycloheptatriene—metal tricarbonyl complexes C7H8M(CO)3 (M = Cr and W); (c) The 1,3,5-cyclooctatriene complex C8H10W(CO)3; (d) The cyclooctatetraene—metal tricarbonyl complexes C8H8M (CO)3 (M = Cr or Fe); (e) The 1,5-cyclooctadiene—metal tetracarbonyl complexes C8H12M(CO)4 (M = Mo or W); (f) The tungsten tetracarbonyl complexes of bicyclo[2,2,1] heptadiene and dicyclopentadiene; (g) The 1,3-cyclohexadiene complexes (C6H8)2M(CO)2 (M = Mo or W); (h) The cycloheptadienol complex (C7H9OH)Fe(CO)3; (i) The methyl vinyl ketone complexes (CH3COCH = CH2)3M (M = Mo or W); (j) A product of composition C12H16Fe(CO)2 obtained from allene dimer and Fe3(CO)12. The following fragmentation processes of particular interest were observed: (a) The facile dehydrogenation of ions containing the π-bonded 1,3,5-cyclooctatriene, 1,5-cyclooctadiene, and 1,3-cyclohexadiene ligands with two adjacent CH2 groups; (b) Elimination of neutral C5H6 fragments from tungsten carbonyl ions containing π-bonded bicyclo[2,2,1] heptadiene or dicyclopentadiene ligands; (c) Facile dehydration of iron carbonyl ions with π-bonded cycloheptadienol.

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.

Partial EI-mass spectra of 3β-hydroxy- and 3β-acetoxy-5α-cholestanes substituted in positions 5α-, 6β- or 5α,6β- with a hydroxyl group or halogen atoms (fluorine, chlorine, bromine) are presented. The molecular ions of 5α,6β-disubstituted derivatives of 3β-hydroxy-5α-cholestane (or of its 3-acetate) are considerably more stable than the corresponding monosubstituted derivatives if at least one of the pair of the vicinal substituents is chlorine or fluorine. This increase in stability, most striking in 5α- and 6β-fluoro compounds, is explained by the inductive effect.
