The preparation and properties of simple metal derivatives of pentachlorothiophenol are described: MSC6Cl5 (M = Na, K, Rb, Cs, TI, Cu, Ag, Au, Ph3Sn, n-Bu3Sn, Ph3Pb, Ph4As), M(SC6Cl5)2 (M = Zn, Cd, Hg, Ni, Pd, Pb, n-Bu2Sn, Sn), Ge(SC6Cl5)4, and Pt(SC6Cl5)3Cl. Non-metallic derivatives of group V, M(SC6Cl5)3 (M = P, As, Sb) and PhP(SC6Cl5)2 have also been prepared from Pb(SC6Cl5)2 and the corresponding non-metallic chloride. The infrared spectra of these compounds and the mass spectra of C6Cl5SH and (C6Cl5S)2 have been examined.

The reaction of dialkyldichlorosilanes with amide oximes leads to cyclic products whose monomeric form has an l-oxa-3,5-diaza-2-silacyclopent-4-ene structure. These compounds exist mostly in adimeric form, occasionally monomeric or trimeric. Their infrared spectra have been interpreted. The secondary amino group of the compounds has been trisilylated.

Resolution Study

A comprehensive low-resolution study of the mass spectra of the compounds C6F5M(CH3)2, where M = N, P, As, is described, fragmentation pathways being assigned with the aid of normal metastable ions and mass analyzed ion kinetic energy spectra (mikes). A comparison of these spectra has re-affirmed the absence of halogen transfer processes for atoms such as N which are incapable of providing the necessary vacant orbitals apparently prerequisite in the mechanisms. The influence of increased coordination to phosphorus and effects on halogen transfer processes are discussed with respect to the mass spectra of the compounds C6F5PX(CH3)2, X = O, S, Se and the gold adducts C6F5P(CH3)2•AuX, X = Cl, Br, I.

Infrared spectra of metal-free phthalocyanine, chlorinated and unchlorinated copper phthalocyanines, and three new metal derivatives of phthalocyanine: MoPc, Na2Pc, and AlOH—Pc (Pc = C32H16N8), have been recorded. Assignments have been suggested for many of the peaks in the infrared spectra of the phthalocyanines.

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.

The effects of chlorine atoms on the fundamental frequencies of the s-triazine ring are discussed and the vibrational assignments in the region 1600–700 cm−1 are extended. The variation in the position of the C3N3-ring bending mode in the region near 810 cm−1 is discussed.
