Alumina sulfuric acid mediated solvent-free and one-step Beckmann rearrangement of ketones and aldehydes and a useful reagent for synthesis of keto- and ald-oximes

摘要

Under solvent-free conditions, one-step Beckmann rearrangement of a variety of ketones and aldehydes could proceed in the presence of alumina sulfuric acid (ASA). The ASA reagent can also be used for the preparation of keto- and ald-oximes.
