Electron impact mass spectra of some bis-(2-benzothiazolyl)furans and bis-(2-benzothiazolyl)thiophenes.
The electron impact mass spectra of some bis-(2-benzothiazolyl)furans and bis-(2-benzothiazolyl)thiophenes have been recorded and the identity of various ions in the mass spectra established. Compounds 1 and 2 present model substances and it is found that their fragmentation pathway is similar to the mono-(2-benzothiazoles). Compounds where the benzothiazolyl groups are directly substituted on the furan nuclei, but in different positions, exhibit two main pathways of fragmentation: fragmentation of the furan nucleus and fragmentation of the benzothiazole nucleus. Other compounds studied show specific fragmentation characteristic for divinyl furan compounds and for compounds with a phenyl substituent between two heterocyclic nuclei.
