1-Phenyl-3-tosyl-1<i>H</i>-pyrrole

Abstract

1-Phenyl-3-tosyl-1H-pyrrole was prepared, in moderate yield, by the electrophilic aromatic substitution of 1-phenyl-1H-pyrrole with tosyl chloride in the presence of excess zinc oxide under solvent-free conditions. A minor product was its isomer, 1-phenyl-2-tosyl-1H-pyrrole.
