Title
Preparation of recoverable Ru catalysts for liquid-phase oxidation and hydrogenation reactions
Abstract

We here report the synthesis, characterization and catalytic performance of new supported Ru(III) and Ru(0) catalysts. In contrast to most supported catalysts, these new developed catalysts for oxidation and hydrogenation reactions were prepared using nearly the same synthetic strategy, and are easily recovered by magnetic separation from liquid phase reactions. The catalysts were found to be active in both forms, Ru(III) and Ru(0), for selective oxidation of alcohols and hydrogenation of olefins, respectively. The catalysts operate under mild conditions to activate molecular oxygen or molecular hydrogen to perform clean conversion of selected substrates. Aryl and alkyl alcohols were converted to aldehydes under mild conditions, with negligible metal leaching. If the metal is properly reduced, Ru(0) nanoparticles immobilized on the magnetic support surface are obtained, and the catalyst becomes active for hydrogenation reactions.

Graphical abstractWe here describe the preparation of a new supported Ru(III) and Ru(0) catalysts with fast recovery and negligible metal leaching for green chemical processes covering both alcohol oxidation and olefin hydrogenation reactions. The reactions were performed under mild conditions with H2 and O2 as green reducing and oxidizing agents, respectively.Figure optionsDownload full-size imageDownload as PowerPoint slide
