Reaction Steps

A reaction mixture was prepared with 3.8g (22 mmol) of m-bromophenol, 20 ml of methanol, and 20 ml of benzene. To this reaction mixture, 20 ml of 1 N KOH was added while N2 gas was passed into the mixture, and the methanol and water were removed at a temperature of 100° C. or below. To the resultant, 20 ml of benzene was added and benzene was distilled off at a temperature of 100° C. or below. Subsequently, 2.18 g (10 mmol) of 4,4'-difluorobenzophenone and 30 ml of dimethylsulfoxide (DMSO) was added and reacted at 140° C. for 4 hours to obtain 3.8 g of 4,4'-bis(3-bromophenoxy) benzophenone. The yield was approximately 72%. The following is the reaction formula of this synthesis. ##STR7##
