Abstract

Proximity effects of the carboxyl group with the phosphorus atom in the molecular ion of (o‐carboxyphenyl)diphenylphosphine (1) leads to the loss of ĊHO to form the base peak at m/z 277, which is totally absent in the (m‐ and p‐carboxyphenyl)diphenylphosphines. The mechanism of the loss of ĊHO and the fragmentation of 1 was investigated in detail using metastable ion, collision‐induced dissociation and high‐resolution studies.

## 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
