Reactions of o-alkenyloxyarenediazonium fluoroborates and related species with nitroxides
Abstract
Treatment of arenediazonium fluoroborates bearing suitable alkenyloxy- or alkenylamino-ortho-substituents affords ring-closed hydroxylamine derivatives via a free-radical mechanism: similar treatment of o-alkynyloxy- or o-alkynylamino-arenediazonium salts gives aldehydes.
