Abstract:3-Chloro-4-(2-bromomethyl-4-1,3-dioxolane-2-yl)phenyl-4′-chlorophenyl ether is an important intermediate of fungicide difenoconazole. 3-chloro-4-(2-bromomethyl-4-1,3-dioxolane-2-yl)phenyl-4′-chlorophenyl ether,which was prepared by bromination and ketal reaction of 2-chloro-4-(4-chlorophenoxy)-aectophenone in one step pathway. The yield was 90%, and purity 95%. The process had several advantages of facile reaction conditions,convenient operation and cheap reagents. |
