• 論文の詳細を見る

• An oxygen transfer from the nitro group to the olefinic double bond followed by a simple cleavage affords intense fragment corresponding to <I>o</I>-nitrosophenylthio cation at <I>m</I>/<I>z</I> 138 during the mass spectral fragmentations of α-(<I>o</I>-nitrophenylthio)cinnamic acid. Single and double oxygen transfers from the nitro group to sulfur lead to concerted ejections of [SO+CO<SUB>2</SUB>] and [SO<SUB>2</SUB>+CO<SUB>2</SUB>] from the molecular ion of this compound. The mechanisms proposed for these processes are supported by high-resolution data, CID linked scan spectra, D-labelling, and chemical evidence.
