Electron Impact Mass Spectra of Some Unsaturated Derivatives of 2-Benzothiazoles

The electron impact mass spectra of some p- substituted styryl-2-benzothiazoles 1-6 and p-substytuted phenyl-butadienyl-2-benzothiazoles 7 and 8 have been recorded and the identity of various ions in the mass spectra established. the compounds 1-6 exhibit one main fragmentation route which include the formation of M-1 ion as the base peak, and after elimination of p-substituted phenylacetylene molecule, the formation of benzothiazole cation. Compound 7 and 8 show the fragmentation pathway which include the formation of butadienyl-2-benzothiazole ion as the base peak.

2-benzothiazoles; (4-phenyl-butadienyl)-2-benzothiazoles
