Chromatomass spectrometric study of mixtures of aromatic diols using column silylation

November 1, 1983
Author(s)
Anzor I. Mikaia, Alla V. Antonova, Vladimir G. Zaikin, Nikolay A. Prostakov, Vladimir Y. Rumyantsev, Evgenyi Slivinsky, Sergai Loktev
A GC-MS method is developed for the study of C 4 -C10 aliphatic diols in complex mixtures. The method includes a GC column trimethylsilylation with N,0-bis(trimethyl­silyl)trifluoroacetamide.

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

September 29, 1983
Author(s)
Anzor I. 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 I. 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 I. 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 I. 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

Ionization and appearance potentials in organic chemistry. 3. Determination of the difference between the enthalpies of formation of cis- and trans-isomers of bicyclo[4.3.0]- nonane and bicyclo[4.4.0]decane Using Appearance Potentials

June 1, 1980
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin
The first adiabatic potentials of the ionization of cis and trans iosmers with respect to the linkage of the rings of bicyclo[4.3.0]nonane and bicyclo[4.4.0]decane are practically identical. for the stereoisomers of these two series have been measured. The

Mass spectrometric investigation of Alkyl-Substituted arylpyridynes

May 1, 1980
Author(s)
Anzor I. Mikaia, Anatolyi Soldatenkov, Vadim Fedorov, Vladimir G. Zaikin, Nikolay A. Prostakov
Electron ionization decomposition of aryl(polyalkyl)pyridines containing is studied. General fragmentation pathways and specific patterns for 2-. 3- and 4-arylsubstituted are identified
