Evidence for Extensive Recombination of the Ring-opened to the Original Cyclic Molecular Ions of 2-Substituted Piperidines and Pyrrolidines after Electron Impact
Zahorszky, Uwe I.

The unusually preferred formation of (M-alkyl)(1+) ions by α-fission of 2,2-dialkyl-substituted N-ethyl-piperidines (2) and -pyrrolidines (3) and the virtual absence of ring degradation products is caused by facile recombination of the ring-opened to the original cyclic molecular ions.Suppression of ring opening of the initially formed molecular ions or conversion of the ring-opened into other isomeric molecular ions as explanations of the mass spectrometric behaviour of (2) and (3) are excluded.
