研磨法合成α,β-不饱和酮
Synthesis of α,β-Unsaturated Ketones by Grinding Method
【摘要】 将苯乙酮、芳香醛与KF Al2 O3 置于研钵中 ,在无溶剂条件下 ,室温研磨 5min后放置一定时间 ,得到收率 94%~ 98%的α ,β 不饱和酮 .该法反应条件温和 ,操作简便 ,KF Al2 O3 可回收再利用
【Abstract】 Using KF Al 2O 3 (basic) as catalyst the Claisen Schmidt condensation of acetophenone with aromatic aldehydes proceeded smoothly by simple mixing and grinding under solvent free conditions at room temperature to give α,β unsaturated ketones in high yields (94%~98%), and KF Al 2O 3 could be recovered and reused.
