“…The formation of acetone oxime is not surprising in light of the fact that oximes have been synthesized from aldehydes and ketones using acid catalyzed transoximations by acetone oxime. 15 No deprotection was observed when cyclohexanone oxime or acetophenone oxime was heated in acetone-H 2 O in the absence of bismuth nitrate, suggesting that the presence of this reagent is necessary for deprotection. A suspension of Bi(NO 3 ) 3 •5H 2 O in water is acidic.…”

Oxime compounds were efficiently synthesized with aromatic or aliphatic ketones and hydroxylamine hydrochloride as raw materials in the PEG-400 solution, using cheap and readily available superfine kaolin as catalyst under microwave irradiation condition. The effects of the catalyst, the solvent type, reaction time, reaction temperature on the reaction were investigated. The structures of the products were detected by melting point, nuclear magnetic resonance, infrared spectroscopy and mass spectrometry data. This method has the advantages of short reaction times (5～15 min), good yields, and simple operation as well as environmental friendliness. In addition, the preliminary experiment shows that superfine kaolin could also catalyze transoximation reaction and preparation of oxime ether compounds under microwave irradiation with the yields of 42%～67% and 59%～72%.
