## Abstract The unusual fragments noticed in the mass spectra of __N__‐benzyl‐ and __N,N__‐dibenzylanthranilic acids have been explained on the basis of the __ortho__ interaction of the carboxyl group with the __N__‐benzyl‐ and __N,N__‐dibenzyl moieties.

## Abstract The mass spectrum of __o__‐picolinotoluidide gives rise to three major fragments at m/z 184, m/z 169 and m/z 168, corresponding to the loss of CO from the molecular ion followed by the loss of ṄH~2~ and ĊH~3~ by independent pathways. It has been shown that the __ortho__ methyl group and

Double oxygen migration to sulphur from the ortho-nitro group leading to eliminations of SO2 and 'S02H from the molecular ions and single oxygen transfer to the olefinic double bond in the sidechain giving rise to the most abundant ion at m/z 138 have been observed in 2-nitrophenyl styryl sulphides
