Popis:	N-Butoxy- and N-propoxy-imines derived fromo-,m-, andp-substituted benzaldehydes (X = F, Cl, Br, I) decompose upon electron impact to the respective aldoximes by loss of C n H2n and competitivelyvia 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.
