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]PF6, [omim]BF4 and [hmim]BF4, comparing to traditional volatile organic solvent. The use of ionic liquids was found to enhance the catalytic properties of the catalysts used.
Highlights
The oxidation of alcohols into corresponding aldehydes and ketones is a crucial transformation in organic chemistry, both with academic and industry relevance [1,2,3,4]
We report effective copper-bisisoquinoline-based catalysts for this purpose
The present work revealed that copper-bisisoquinoline-based catalysts has potential applications in the oxidation of alcohols into corresponding aldehydes and ketones with excellent conversion and good selectivity
Summary
The oxidation of alcohols into corresponding aldehydes and ketones is a crucial transformation in organic chemistry, both with academic and industry relevance [1,2,3,4]. Room-temperature ionic liquids [11] are finding growing applications as alternative reaction media for separations [12] and organic transformations [13,14,15,16,17,18,19,20,21]. We report effective copper-bisisoquinoline-based catalysts for this purpose.
