Sažetak
The electron impact mass spectra of some benzo[b]thiophene- and thieno[2, 3-b]thiophene-2, 5- dicarbonyldichlorides, 2, 5-dicarbonyldianalides, 9- anilido- benzo[b]thienyl[2, 3-c]quinolones and 9- anilido-thieno[4, 5-b′]thienyl[2, 3-c]quinolones are discussed. Dominant peaks in dianilides are formed by cleavage of the CN bond on one side of the anilido group, as well as on the anilido group itself in anilidoquinolones. These ions fragment further by the cleavage of a CC bond in dianilides and the CONRPh group is lost directly, while the quinolonic part of the molecule in quinolones fragments with low probability. Characteristic fragment ions of dicarbonyldichlorides arise by the cleavage of the CCl bond.
