It is shown that thiophene-1,l-dioxides carrying an alkyl chain in the 2-and +positions can be readily distinguished by the characteristic fragmentation mode of the latter, viz. benzylic cleavage of the side-chain with back-transfer of two hydrogen atoms (I M --CnHIn-, 1 '). By deuterium labelling i
