ETUDE DE LA FRAGMENTATION PAR IMPACT ELECTRONIQUE DE DERIVES DU BENZOTHIAZOLE

Article abstract of DOI:10.1002/hlca.19800630318

The mass spectra of eighteen substituted benzothiazoles are reported and discussed.All these compounds are thermodynamically stable and give an intense molecular ion, which undergoes different types of fragmentation depending on the nature of the substituent which is rarely eliminated directly. β-Cleavage with respect to the heterocyclic double bond is often obseved.Specific 2H-, 13C-, 15N- and 34S-labelling have been used in order to confirm the fragmentation patterns.
