Abstract

Abstract: 4-Chloro, 4’-Hydroxy Benzophenone (I) was prepared in 71-72% total yield and >99.5% purity. A one pot synthesis of I by acylation of phenol with 4-Chloro, 4’-Hydroxy Benzophenone in the presence of AICI3 and workup of the reaction mass to give Crude (I) in >95% purity and Yield of 85%. Crude (I) was further purified to give>99.5% pure (I). Thus to Phenol dissolved in ODCB is added AICI3. To this is added 4-Chloro, 4’Hydroxy Benzophenone, and the whole mass maintained at 80 C for 12 hours. The reaction mass is worked up by drowning in dilute HCI solution and Crude (I) of purity>95% ppts. out. This is further purified by to give>99.5% pure material in 71-72% yield.
