- Abstract
An SN2-type fragmentation was observed on mass spectrometric analysis of N-(ω-X-alkyl)-2-alkylpiperidines (X = NRCOR′, CONH2, COOR, NH2). The molecular ion after loss of the 2 alkyl substituent on the piperidine ring may eject the neutral piperideine on attack of the substituent X on the α-carbon of the N-substituted alkyl-chain. Through this process a cyclic fragment ion is formed. The influence of its ring size and of the substituent X on the stability of this fragment was investigated. The SN2 reaction is favoured in the case of production of five- and six-membered rings.
