ELCTRON IMPACT MASS SPECTRA OF SOME 2',3'-, AND 4'-SUBSTITUTED THIOPHENE-2- AND 3-CARBOXANILIDES

The electron impact mass spectra (EI/MS) of 2- and 3-carboxanilides are dominated by the peak due to the corresponding thenoyl cations formed by cleavage of the C-N amide bond.This reaction is not affected by the polar effect of the substituents present in the phenyl ring.Most of the 2'-substituted derivatives undergo a cyclisation reaction with ejection of the substituent.In addition, for 2'-methyl and 2'-ethyl derivatives of both series of thiophene anilides a cryptic "ortho"-effect was suggested as responsible of the charge retention in the aniline moiety.
