Diisopropoxyaluminium trifluoroacetate/4-nitrobenzaldehyde - A new Oppenauer oxidation system for accelerated oxidation of secondary alcohols to the corresponding ketones
A practical, efficient and accelerated oxidation of secondary alcohols to the corresponding ketones has been achieved at rt in high yields by a modified Oppenauer oxidation system using diisopropoxyaluminium trifluoroacetate as catalyst and 4-nitrobenzaldehyde as a hydride acceptor.
