Abstract


Oxime is an important class of organic intermediates, can be used for the preparation of an amine , an amide , an oxazole ( isoxazole ) , pyridine, nitrones , a nitrile , an oxime ether compound . In accordance with the type of reaction , the oxime in recent years the organic reactions such as deoximation , reduction , dehydration , Beckmann rearrangement and etherification reaction progress . Primarily montmorillonite K10 solid containing ammonium chlorochromate in methylene chloride as the oxidant oxidation oxime , ultrasound irradiation under the one-pot method of sulfamic acid and zinc chloride catalyzed the the oxime synthesis of aryl dimethylacetamide and Beckmann rearrangement of the oxime in acetonitrile . Compared with the method reported in the literature , the post-processing operation is simple , the reaction time is shortened to improve the reaction yield .
