ABSTRACT:
Processes for preparing 1-dichloroacyl-4-(substituted phenoxy)benzenes and intermediates therefor. The processes are characterized by the use of certain catalysts, solvents and reaction conditions which afford improved yields and reaction products which can be purified by simple procedures (e.g. extraction, crystallization, etc.). The processes are especially applicable to manufacturing large quantities of the aforementioned compounds. The products are useful as mite ovacides.
