C–N Coupling of Amides with Alcohols Catalyzed by N-Heterocyclic Carbene–Phosphine Iridium Complexes
During thelast20-30 years, palladium-catalyzed reactions have witnessed tremendous advances in the industrial and organic reactions such as hydrogenation, coupling, cyanation and amination. Despite the wide utility of Pd-catalysts in these reactions, they suffer from a number of drawbacks such as recovery, reuse of catalyst and remain as a contaminant in the products at the end of the reaction...
Carbon catalyst consisting of a hybrid structure made up of amorphous carbon and nanographite was prepared from the leaves of Pinus Roxburghii. The catalyst was prepared through sodium hydroxide and hydrochloric acid treatment of the dried pine leaves; and further functionalized with sulfuric acid treatment to incorporate the acidic functionalities. The synthesized catalyst was characterized by...
