Abstract:The synthesis process of 2-Chloro-4-(4-chlorophenoxy)-acetophene that was a new important intermediate of difenoconazole was described.p-Chlorophenol and 2,4-dichloroacetophenene under the catalysis of copper was condensed to give the product,and the total yield was 71.4%.This process can meet the industrialized production due to the fact that the method had high yield,easy operation and low cost.
Key words:2-Chloro-4-(4-chlorophenoxy)-aectophenone; Difenoconazole; Synthesis
