Letter: Electron Ionization-Induced Fragmentation of New Thiochalcone Derivatives

Abstract

Electron ionization mass spectral fragmentation of new (E)-4-chalconylothioalkyl substituted derivatives of piperidinie, 4-methylpiperidine, morpholine and piperazine as well as (E)-4-bromoalkylthiochalcones being substrates of the former compounds have been studied. Fragmentation pathways have been proposed on the basis of the accurate mass and metastable transition measurements.
