Heterogeneous copper catalyst for the cycloaddition of azides and alkynes without additives under ambient conditions.

A new copper catalyst was developed by immobilizing copper nanoparticles in aluminum oxyhydoxide fiber. The catalyst showed high catalytic activity for the (3+2) Huisgen cycloaddition of nonactivated alkynes as well as activated ones with various azides at room temperature. The catalyst was recycled five times without significant loss of activity.

One-Pot Synthesis of Imines and Secondary Amines by Pd-Catalyzed Coupling of Benzyl Alcohols and Primary Amines

Imines and secondary amines were synthesized selectively by controlling reaction conditions for the Pd-catalyzed one-pot reactions of benzyl alcohols with primary amines. The reactions did not require any additives and were effective for a wide range of alcohols and amines.

Rhodium nanoparticles entrapped in boehmite nanofibers: recyclable catalyst for arene hydrogenation under mild conditions

A new recyclable rhodium catalyst was synthesized by a simple procedure from readily available reagents, which showed high activities in the hydrogenation of various arenes under 1 atm H2 at room temperature.
