Aqueous room-temperature gold-catalyzed chemoselective transfer hydrogenation of aldehydes.

Reduction of aldehydes to the corresponding alcohols is one of the most fundamental and useful reactions that are important in the pharmaceutical and chemical industry. Among the various available reduction protocols for the synthesis of valuable hydroxy compounds, catalytic transfer hydrogenation (TH) has emerged as the most viable, mainly due to the non-involvement of highly flammable and exp...

-Solid Lithium Perchlorate, a Highly Efficient and Chemoselective Catalyst for the Acetalyzation of Aldehydes

-A simple, efficient, and general method has been developed for the chemoselective acetalization of aldehydes with 1,3-propanediol, 1,2-ethanediol and trimethyl orthoformate in the presence of solid lithium perchlorate under solvent-free conditions. Both cyclic and acyclic acetals of aldehydes were obtained under environmentally benign conditions in good to excellent yields.

Highly efficient transformation of levulinic acid into pyrrolidinones by iridium catalysed transfer hydrogenation.

Levulinic acid (LA) is transformed into pyrrolidinones via iridium-catalysed reductive amination using formic acid as the hydrogen source under aqueous conditions. The catalytic system is the most active and performs under the mildest conditions ever reported for the reductive amination of LA.

Liquid-Phase Hydrogenation of Unsaturated Aldehydes: Enhancing Selectivity of Multiwalled Carbon Nanotube-Supported Catalysts by Thermal Activation

Carbon materials are nowadays one of the most commonly used materials in catalysis and can be used either as a support for different heterogeneous catalysts or as a catalyst themselves. Carbon nanotubes (CNTs) were discovered soon after the successful laboratory synthesis of fullerenes. Since their discovery in 1991 by Iijima, CNTs have been the focus of materials research as a result of their ...
