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.

Liquid And Solid Phases

A correlation between the infrared absorption spectra and the structure of 13 N-mono- and N-di-substituted trichloroacetamidines is presented. N-Alkyl- and N-aryl-trichloroacetami-dines associate strongly in the liquid and solid phases, and exist only in the imino form in non-polar solvents. They can be characterized by a strong band (amidine II band) at 1510–1525 cm−1 and 1570–1580 cm−1 respectively which is attributed to the deformation vibration [Formula: see text] of the secondary amino group. The degree of association of N-substituted trichloroacetamidines changes in the following order of substitution:[Formula: see text]

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.

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.

The infrared spectra of a number of secondary bases and of their salts have been examined. The spectra of the salts differ from those of the corresponding bases in containing several absorption bands that are absent from the latter. Those of the new bands occurring in the region 1620 to 1560 cm.−1, which are due to NH2+ deformation vibrations, are characteristic of secondary amine salts, and can be used to detect the presence of a secondary amino group in the original molecule. With aromatic bases the spectra are complicated because the ring absorption occurs in the same region, but in many cases the assignment can still be made, although with less certainty. In zwitterionic substances such as the secondary aliphatic amino acids, the function is more difficult to detect.
