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.

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.

Magnetically separable Pd catalyst for highly selective epoxide hydrogenolysis under mild conditions.

A magnetically separable palladium catalyst was synthesized simply through a sol-gel process incorporating palladium nanoparticles and superparamagnetic iron oxide nanoparticles in aluminum oxyhydroxide matrix, which is highly active and selective for epoxide hydrogenolysis at room temperature under 1 atm H2. The catalyst was recycled for 25 times without loss of the activity.

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.

Air-stable racemization catalyst for dynamic kinetic resolution of secondary alcohols at room temperature.

[reaction: see text] A novel racemization catalyst was synthesized for the dynamic kinetic resolution (DKR) of alcohols with a lipase at room temperature in the air. Furthermore, a polymer-supported derivative was also synthesized and tested as a recyclable catalyst for the aerobic DKR of alcohols.

Palladium nanoparticles entrapped in aluminum hydroxide: dual catalyst for alkene hydrogenation and aerobic alcohol oxidation.

[reaction: see text] A new aluminum hydroxide-supported palladium catalyst (1) made by a one-pot synthesis through nanoparticle generation and gelation shows a dual catalytic activity for olefinic hydrogenation and aerobic alcohol oxidation.
