Klyba, V. Bochkarev, L. Brandsma, O. Tarasova, N. Nedolya, B. Trofimov] The influence of the position and nature of the substituent in the thiophene ring on the fragmentation of 3-alkyl- and 5-alkyl-2-thienylamines under electron impact was studied. The derivatives containing the ethyl group in position 3 decompose due to both the elimination of the fragments from the substituents and thiophene ring rupture. In the case of the compounds with thetert-butyl group in position 5, the last process is not observed. The fragmentation of the 3- and 5-methyl-substituted derivatives occurs mainly from the isomeric thiopyran form of the molecular ion.
