## Abstract Under electron impact, 6βthiotheophyllines eliminate various fragments from the pyrimidine moiety. In a retro DielsβAlder reaction, they lose the fragment Xο£ΎCο£ΎNCH~3~ from positions 1 and 2 of the pyrimidine ring. In 6βsulfinyltheophyllines, the sulfinyl group is the main target for frag
