Palladium-catalyzed oxidative cross-coupling for the synthesis of α-amino ketones.

A novel oxidative cross-coupling reaction for the synthesis of α-aryl α-amino ketones in the presence of palladium catalysts using T+BF4 - as an oxidant has been developed. This transformation was achieved by direct C-H oxidation of α-aminocarbonyl compounds and arylation. The mild reaction has a broad reaction scope and gives desired α-aryl α-amino ketones in moderate to excellent yields.

Transformation of cellulosic saccharides into alkyl glucosides catalyzed by bifunctional ionic liquids.

Three kinds of hydrophobic/acidic bifunctional ionic liquids, which contain two different anions, were synthesized and utilized as catalysts for the conversion of cellulosic saccharides into alkyl glucosides, which exhibit a high catalytic conversion for cellobiose and cellulose with a low degree of crystallinity; the catalyst can be easily recovered and reused.
