摘要:在六钥酸和节墓三乙墓氯化按(BTEAC)的复合催化作用下，以芳香醛为原料，分别与1,3一环己二酮和5,5-二甲墓-1,3一环己二酮在乙睛溶剂中，通过缩合反应得到一系列高产率氧杂葱二酮类衍生物;并在此墓础上探讨了合成该类化合物的最佳反应溶剂、最佳催化剂、最佳稳定剂及其用量等，同时验证了该催化体系可重复使用5次而催化活性无明显降低最后提出了可能的反应机理 Abstract: Aromatic aldehyde was used as raw material to synthesize 1,3-cyclohexanedione and 5,5-dimethyl-1 , 3-cyclohexanedione in acetonitrile solvent, through condensation reaction to obtain a series of high-yield oxygen onion dione derivatives; and in this on the basis of the synthesis of these compounds to explore the best reaction solvent, the best Catalyst, the best stabilizer and the amount of its use, at the same time verify that the catalytic system can be reused five times without significant reduction in catalytic activity and finally proposed a possible reaction mechanism
