(2-(Phenoxycarbonyl)phenyl)boronic acid is a boronic acid catalyst from the Hall Group developed for chemoselective activation of oxime N−OH bonds for the preparation of functionalized amide compounds via Beckmann Rearrangement. This catalyst is efficient to transform various diaryl, aryl-alkyl, heteroaryl-alkyl, and dialkyl oximes to amide products under ambient conditions.
