Isolongifolenone oxime was prepared from isolongifolenone and hydroxylamine hydrochloride by oximation reaction. Effects of the reaction conditions on the yield of isolongifolenone oxime were investigated by single factor method and ortnogonal experiments. The optimum reaction conditions were as follows:sodium acetate as the catalyst, the molar ratio of isolongifolenone, hydroxylamine and sodium acetate 1:1.3:0.55, reaction temperature 76 ℃ and reaction time 6 h. The yield of isolongifolenone oxime reached 99.0% under the optimum reaction conditions.The structure of the isolongifolenone oxime was determined by FT-IR, 1H NMR, GC-MS and single crystal X-ray diffraction. Complexation properties of isolongifolenone oxime on metal ions including Cu2+, Co2+, Cd2+, La3+, Pb2+, Ag+ were examined, and the results showed that isolongifolenone oxime exhibited better complexing effect to Cu2+ than that to other metal ions. It was also known from the FT-IR that the complexation between Cu2+ and isolongifolenone oxime was formed by Cu-N and Cu-O coordination bonds.

Key words: isolongifolenone oxime, isolongifolenone, oximation, metal complex
