Abstract

Low‐resolution mass spectra, and where appropriate complete high‐resolution mass spectra, were recorded for 29 2,3‐disubstituted 4‐quinazolones. Rationalizations are presented for the principal fragmentation modes of this series of aromatic compounds. Four of the 4‐quinazolones which contain a vinyl‐2‐furanyl group attached to C‐2 of the heterocyclic ring exhibited an unusual loss of C~3~H~2~O from their respective molecular ions.

The electron impact fragmentations of some cyclotetraphosphazenes are reported and discussed. The major fragmentation path involves loss of two amine radicals and one chlorine radical in the series PfiN,Ck,(NMe2), when n = 2, and subsequent stages involve a ring contraction process with elimination

The fragmentation behaviour of 18 vicinally substituted aminonitropyridines was studied under electron impact conditions. The decomposition patterns were found to be strongly dependent on the position of substituents The formation of the am analogue of carbazole seems phenylamioopyridine.
