Highly dispersed copper iodide on activated carbon (CuI/C) solid catalyst has been investigated for the Paal–Knorr condensation
of γ-diketones with aliphatic, aromatic and heterocyclic amines under solvent-free conditions; which lead to the formation of N- substituted
pyrrole derivatives in excellent yields. This simple experimental procedure combined with easy recovery and reusability of the
catalyst is expected to contribute to the progression of a clean and ecofriendly strategy for the synthesis of N-substituted pyrrole derivatives.
Keywords: CuI/C, Heterogeneous catalyst, Paal–Knorr condensation, N-Substituted pyrroles, Solvent-free, Montmorillonite, anhydrous Na2SO4, N-substituted pyrroles, substituents, hexadecylamine.
