Abstract
Abstract Alkyl 1 H-pyrrole-2-carboxylates and dialkyl 1 H-pyrrole-2, 5-dicarboxylates were synthesized in quantitative yield by reactions of 1 H-pyrrole, 2-acetyl-1 H-pyrrole, and 1- methyl-1 H-pyrrole with carbon tetrachloride and aliphatic alcohols in the presence of iron- containing catalysts. A probable reaction mechanism was proposed, and the rate constants and energies of activation of particular steps were determined on the basis of ...
