Abstract
By using the technique of microwave-assisted synthesis,o-Hydroxybutyrophenone(o-HBP) was prepared by phenylbutyrate(PB) via Fries rearrangement.The influences of reaction temperature,reaction time and catalyst dosage on the yield were also discussed based on single-factor experiments.According to results of orthogonal experiments,the optimal reaction condition was determined.Under the conditions,PB was converted completely and the yield of o-HBP was 45.0% at 120℃ for 8 min in the presence of 1.6 times AlCl3.
