| Abstract: | The electron impact induced mass fragmentation of 23 new sulphur-containing heterocycles: Thieno [3,4-d] pynmidine-2, 4-dione derivatives are presented. The elucidation of the fragmentation pathways is described. The fragmentation routes have been confirmed by accurate mass measurements and B/E, B~2/E linked-scan spectra. MS experiments show that the characteristic fragments are m/z 73 and 68 in N~1-alkyl derivatives, m/z 215 and in N~1-alkyl derivatives. |
