Abstract

Abstract:

It is reported herein a novel debenzoylation of diaryl ketones. The effect of the additives, catalysts, and temperature were studied carefully. The results indicate that the yield of this transformation can reach up to 72% under the standard conditions∶ n(ptoluenesulfonic acid)∶n (starting material)=1∶100, n(ethylene glycol)∶n(starting material) =3∶1, toluene, 80 h under reflux. This reaction provides a new method for the debenzoylation of diaryl ketones.

Key words: Aryl ketones, Benzoyl, Catalyst, Additives, Temperature

摘要： 研究了新型芳酮类化合物脱除苯甲酰基的反应, 考察了助剂、催化剂及反应温度对反应的影响。实
验结果表明, 以2 - 乙氧基 - 4 - ( ( 4 - 乙烯基苄基) 氧基) 苯基) 苯甲酮为原料, 以甲基苯磺酸为催化剂( n( 对甲基苯磺酸)
∶n( 原料) =1∶1 0 0) , 以乙二醇作为助剂( n( 乙二醇) ∶n( 原料) =3∶1) , 以甲苯为溶剂, 在回流条件下反应8 0h,
得到脱除苯甲酰基的产物1 - 乙氧基 - 3 - ( ( 4 - 乙烯基苄基) 氧基) 苯, 产率为7 2%。该反应为芳酮类化合物脱除苯甲酰
基提供了新的方法。
