Reaction gas chromatography-mass spectrometry is applied to establish optimal conditions for the synthesis of bi- and polycyclic hydrocarbons. Further optimization of the reaction was carried out in a pilot plant.

Mass spectrometric study of 1,2,4- and 1,3,4-oxadiazoles containing indole substituents.

April 1, 1986
Author(s)
Anzor Mikaia, Rosa Ushakova, Vladimir G. Zaikin, VI Kelarev, GA Shveikhgeimer
Under electron ionization major fragmentation pathways for indolyloxadiazoles proceed via cleavage of C-O, C-N and N-O bonds in the oxadiazole ring. Skeletal rearrangements due to a migration of aryl groups are detected for diaryl1,3,4-oxadiazoles.

Silylation of carbonyl compounds in a chromate-mass spectrometer column

March 1, 1986
Author(s)
Anzor Mikaia, Alexey Yatsenko, Leonid S. Glebov, Vladimir G. Zaikin
General and specific fragmentation pathways of trimethylsilyl derivatives of ketones and aldehydes under electron ionization are determined. The derivatives are obtained as a result of on-column silylation.

Chemical methods in organic mass spectrometry

January 1, 1986
Author(s)
Anzor Mikaia, Vladimir G. Zaikin
The book describes various derivatization approaches employed prior GC-MS experiments for structure elucidation of organic compounds.

Mass Spectrometry of Organic Compounds

January 1, 1986
Author(s)
Anzor Mikaia, Vladimir G. Zaikin, Nikolai Vul'fson
Tutorial book on mass spectrometry, instrumentation and mainly fragmentation of organic compounds.
