N-Tosylpyrroles can be very efficiently converted into the corresponding 2-acylpyrroles by reaction with carboxylic acids and trifluoroacetic anhydride; little or none of the isomeric 3-acyl derivatives are formed.

oxidative C-2 arylation followed by sulfonylmigration is described. The simple, easyaccess to the highlyfunctionalized free-NH pyrroles secures opportunities for the preparation of compounds with promising biological activities in contemporary organic synthesis. The event of sulfonylmigration from pyrrole-N to C-3 is thermodynamically favored as revealed by density functional methods. The different plausible
