N-Butoxy- and N-propoxy-imines derived from o-, m-, and p-substituted benzaldehydes (X = F, Cl, Br, I) decompose upon electron impact to the respective aldoximes by loss of CnH2n and competitively via 1,5-distonic radical cations by loss of CH2O to 1,3-distonic ions which eliminate H-. and/or a halogen atom in the course of homolytic aromatic substitution, giving rise to cyclic (M-CH2O-H-.)(+) or (M-CH2O-X-.)+ ions.
