Abstract
The electron impact mass spectra of some 1-(2-furyl)- and 1-(2-thienyl )-2-(2-benzothiazolyl) ethenes have been recorded and the identity of various ions in the mass spectra established. The compounds examined ( 1-10) exhibit two main fragmentation routes. On one hand, fragmentatio n of the furan and thiophene nuclei and the formation of cyclopropenyl ethyne cations with very significant abundance and on the other hand, fragmentation of the benzothiazole nuclei on characteristic pathways. Compounds 6-10 also show two additional fragmentation routes.
