Tandem nucleophilic addition–Oppenauer oxidation of aromatic aldehydes to aryl ketones with triorganoaluminium reagents†
Abstract
In the presence of pinacolone, the in situ prepared triorganoaluminium reagents reacted with aromatic aldehydes to give ketones in moderate to high yield. We propose that the products are formed via a tandem organoaluminium reagents addition–Oppenauer oxidation sequence.
