Green Catalytic Synthesis of the Pyrroles by N and P Functionalized Activated Carbon supported Ir

Abstract

Pyrroles are a significant class of nitrogen-containing heterocyclic compounds and the derivatives. Here, an efficient procedure has been proposed for the loading of Ir on N, Pdoped activated carbon to exploit pyrroles are synthesized from alcohols and amino alcohols. And the optimal conversion of 1-phenylethanol is up to 65 % with 2-phenylpyrrole selectivity of 80 %. The good performance is attributed to the interaction between metal Ir and N, P-doped activated carbon, which could also be confirmed from BET and XPS characterizations. What's more, the catalyst could be generally used for a range of reactions to produce pyrroles from alcohols and amino alcohols.
