Mass Spectrometry of Small Cycles (C,Si,Ge)

September 29, 1983
Author(s)
Anzor Mikaia, Vladimir G. Zaikin, Valentin Vdovin
Decomposition of cyclopropane and cyclobutane containing compounds with Carbon, Silicon and Germanium atoms under mass spectrometry conditions is discussed.

Reaction chromato-mass spectrometry when studying cyclopropane compounds

May 1, 1983
Author(s)
Anzor Mikaia, Lyudmila Medvedkova, Vladimir G. Zaikin, Valentin Vdovin, A Kamisheva
A GC-MS method for structure elucidation of cyclopropane compounds is developed. The method includes the use of hydrogenolysis microreactor in the inlet system of a GC-MS and H2 or D2 as carrier and reagent gas.

Nitration of alkyl substituted 4-aryl(benzoyl)pyridynes

May 1, 1982
Author(s)
Anzor Mikaia, Nikolay A. Prostakov, Anatolyi Soldatenkov, AP Krapivko, AA Fomichev, AA Ustenko
Peri-effect leading to a base peak of [M-NO2] ion in the spectra of dinitro diarenes is described along with the synthesis of arylpyridines

Effects of stereoisomerism in the mass spectra of 2,4-disubstituted thiacyclohexanes

July 9, 1980
Author(s)
Anzor Mikaia, Elena Trusova, Lyudmila Perepelitchenko, Vladimir G. Zaikin
The stereospecificity of fragmentation for isomeric dialkyl- and methyl,phenylthiacyclohexanes under electron ionization are established. Experimentally obtained relative Ionization and appearance energies for the stereoisomers are in agreement with
