Employing bio-waste caffeine carbon-supported heterogeneous cobalt catalyst, synthesis of various substituted pyrrole derivatives is reported. In this methodology, pyrroles were synthesized through coupling between nitroarenes and alkenyl diols in a tandem manner. Among all the heterogeneous catalysts Co(OAc)2-CC-800 displayed the highest catalytic activity. Preparative scale synthesis of pyrroles and synthesis of anti-tubercular agent 5-(4-(1H-pyrrol-1-yl)phenyl)-1,3,4-oxadiazole-2-thiol revealed the practical applicability of this protocol. Several kinetic experiments and Hammett studies were conducted to understand the probable mechanism and electronic effects on this transformation.

A new and efficient methodology to synthesize N-substituted pyrrole derivatives by Clauson Kaas reaction employing Oxone as catalyst was developed. The transformation was performed in acetonitrile under microwave irradiation. This procedure has several advantages such as high yield, clean product formation, and short reaction time.

Synergistic effects of bimetallic Ni and Cu supported on metal-organic polymer composites based on Wells-Dawson P2W18O626- clusters as photosensitizer units were identified, and we report a novel approach for addressing these issues for dehydrogenation and hydrogen production reactions.
