In this present study, the synthesis of 4-(benzyloxy)biphenyl has been successfully carried out using 4-phenylphenol and benzyl chloride in the presence of ultrasonic power (40 kHz, 300W) along with synthesized multi - site phase - transfer catalyst viz., N1,N2-dibenzyl-N1,N1,N2,N2-tetramethylethane-1,2-diaminium dibromide (MPTC). The pseudo first-order kinetic equation has been applied to describe the organic reaction. The various kinetic parameters on the preparation of 4-(benzyloxy)biphenyl has been carried out under ultrasonic frequency condition and synthesized multi - site phase transfer catalyst. Sonication has resulted in better selectivity, high yield, avoids the use of the high temperature, side products and reduces the time consumption. The activation energy (Ea) has been calculated from the experimental results.
