• Mass spectra of p-(tolylsulfonyl)diazines(Ar-SO<SUB>2</SUB>-C<SUB>6</SUB>H<SUB>4</SUB>-CH<SUB>3</SUB>, I) were examined. The molecular ion (M<SUP>+</SUP>) of I seems to undergo the migration to form the rearranged molecular ion of p-tolyl diazinesulfinate(M<SUB>1</SUB>) or that of diazinyl p-toluenesulfinate(M<SUB>2</SUB>). The general fragmentation patterns of M<SUP>+</SUP>, M<SUB>1</SUB><SUP>+</SUP> or M<SUB>2</SUB><SUP>+</SUP> are summarized by some pathways. The principal fragments of I are C<SUB>7</SUB>H<SUB>7</SUB><SUP>+</SUP> formulated as the tropylium ion, Ar<SUP>+</SUP> formed by the loss of p-tolylsulfonyl group from M<SUP>+</SUP>, C<SUB>7</SUB>H<SUB>7</SUB> and ArC<SUB>7</SUB>H<SUB>7</SUB><SUP>+</SUP> yeilded by the expulsion of sulfur dioxide from M<SUP>+</SUP>. It shows that the principal fragmentation of I proceeds by the pathway having the stable fragment ions.
