Resumé

Enol-Keto tautomerism in a new novel series of naphthylidineaniline Schiff bases were studied using their mass spectrum. Two model compounds, namely, salicylidineaniline (Model compound 1, series 1) and naphthylidinequinolinamine Schiff base (Model compound 2, series 4) were used to represent the enol and the keto forms. The mass spectra of the novel series (compounds 4–12) (series 3) are compared with compound 3 which is a representative compound of series 2. The mass spectral measurements reveal the fragmentation pattern in all the new series compounds. It was found that the fragmentation in the new series (series 3) resembles that of the series 2.
