| Abstract: | The decomposing molecular cations derived from (substituted) 2-nitrothiobenzamides fragment by complex rearrangement reactions. When the alkyl substituents (R) attached to N are methyl, the major fragmentations are M]+˙ → M? SO]+˙ and M? SO]+˙ → (M? SO)+˙–R˙]+. This remains a basic pathway when R ? Et, but other rearrangements are also observed. For example, when R=Et, additional competitive processes are M]+˙ → M? HO˙]+ and M]+˙ → M? C2H4O]+˙. |
