## Abstract The mass spectra of alkyl‐ and chloropyrimidines are recorded. A generalised fragmentation mechanism for the derivatives of pyrimidine is proposed. The principle of α‐cleavage for heterocyclic compounds as proposed in the previous paper is shown to be valid for pyrimidine derivatives. E
## Abstract The fragmentation of the β‐ketosulfone‐γ‐methylsulfonyl‐γ‐benzoylbutyronitrile under electron bombardment follows a number of different pathways: formation of the benzoyl ion (Major path); remova of acrylonitrile; liberation of the methylsulfonyl radical or of methylsulfonic acid; and f
