An efficient protocol for deprotection of oximes to carbonyl compounds catalyzed by anhydrous AlCl3 supported on nano silica

摘要

Recovery of aldehydes and ketones from oximes is one of the most important reactions in organic synthesis, because oximes are served as an efficient protective group for carbonyl compounds. We report here an efficient and rapid deoximationmethod using nano SiO2-AlCl3 system, for conversion of various oximes to the corresponding carbonyls under solvent-free conditions.
