✦ Synopsis

The electron impact-induced fragmentation patterns of 3,5-diphenyl-lH-l,2,4-[ 4-"N 1 triazole, 4-ethyl-3,5diphenyl-4H-1,2,4-[ 4-"N] triazole, l-ethyl -3,5-dipbenyl-lH-1,2,4-[ 4-"N 1 triazole and the corresponding unlabelled compounds were established from exact mass measurements and from metastable ion evidence. Evidence for two fragmentation mechanisms was established for the formation of the m/z 104 peak in the spectrum of the 4-ethyl compound. Only the 1-alkylated triazole exhibited an intense peak at m/z 131. Major peaks at m/z 221 (222) and 118 are characteristic of the investigated triazoles.

The modes of fragmentation of perchlorylbenzene (C6H6C10s) and its perdeutero derivative under electron impact are reported and discussed. The occurrence of the [C,H,O]and [C,H,O]+ ions is accounted for in terms of a novel phenyl migration from chlorine to oxygen.
