Mass-spectrometric study of sulfenamide derivatives of 2-substituted benzothiazoles


It is shown that the dissociative ionization of 2-mercaptobenzothiazole derivatives with a sulfenamide bond is accompanied by cleavage of the labile N-S bond and simultaneous migration of the hydrogen atom from the thiol substituent at the site of cleavage to the sulfur atom. Ion peaks with mass 167, 166, R, and (R-H), where R is an N-substituted cycloalkylamine, are maximum peaks and are used for the identification of the compounds.
