Zhu, Chen published the artcileMild and Rapid Hydroxylation of Aryl/Heteroaryl Boronic Acids and Boronate Esters with N-Oxides, Product Details of C7H8BClO2, the publication is Organic Letters (2012), 14(13), 3494-3497, database is CAplus and MEDLINE.
Aryl and heteroaryl boronic acids and boronate esters are rapidly, often within minutes, transformed into the corresponding phenols by N-oxides in an open flask at ambient temperature This transformation has broad compatibility with a variety of functional groups.
