A new type of amine fragmentations under electron impact is elucidated for proline, sarcosine and aspartic acid derivatives and aminomethylphosphines of the general formula R2NCH2X.Ordinary α-cleavage affording the R2N+=CH2 ion is suppressed by elimination of a neutral HX particle and + ion formation, or M-HX neutral particle ejection and generation of an + ion from +.Such fragmentation is ensured by the presence of an α-heteroatom (N, O, P, S) in one substituent (X) and CO2R type delocalizing group in the α-position of the other substituent (R2N).
