Mass spectrometry of derivatives and heterocyclic analogues of 9,10-dihydroanthracene

January 1, 1991
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin, Alexey V. Varlamov, Nikolay A. Prostakov
Fragmentation of derivatives of 9,10-dihydroanthracene and of its heterocyclic analogues containing atoms of O, S, N, P, Si, As, Se and Te at positions 9 and/or 10 is examined. The conditions reviewed are electron impact and chemical ionization in positive

A method for the synthesis of N-alkylpiperidynes.

June 27, 1990
Author(s)
Anzor I. Mikaia, George A. Kliger, OA Lesik, EV Marchevskaya, Vladimir G. Zaikin, Leonid S. Glebov, Sergai Loktev
Reaction gas chromatography–mass spectrometry is applied to establish optimal conditions for the synthesis of N-alkylpiperidynes. Further optimization of the reaction was carried out in a pilot plant.
