Efficient copper-bisisoquinoline-based catalysts for selective aerobic oxidation of alcohols to aldehydes and ketones

Abstract

The selective oxidation of alcohols with molecular oxygen was efficiently completed in high conversion and selectivity using copper-bisisoquinoline-based catalysts under mild reaction condition. The effects of various parameters such as reaction temperature, reaction time, oxidant, ligands, etc, were studied. Solvent effect has been as well studied in ionic liquids [bmim]PF 6, [omim]BF 4 and [hmim]BF 4, comparing to traditional volatile organic solvent. The use of ionic liquids was found to enhance the catalytic properties of the catalysts used. © 2007 by MDPI.
