| Abstract: | Treating 2,5-dimethyl-4-ethoxycarbonyl- and 2,5-dimethyl-4-carboxypyrroles with iodine furnished 3-iodo-2,5-dimethyl-4-ethoxycarbonyl- and 3,4-diiodo-2,5-dimethylpyrroles. It was established that 3-iodo-2,5dimethyl-4-ethoxycarbonylpyrrole reacted at heating with silver nitrite to afford 2,5-dimethyl-3-nitro-4-ethoxycarbonylpyrrole, and the same reagent oxidized 3,4-diiodo-2,5-dimethylpyrrole to give 3,4-diiodo-2-methyl-5-formylpyrrole. |
