Synthesis of benzyl cinnamate catalyzed by triethylamine under microwave irradiation

With sodium cinnamate and benzyl chloride as raw material,triethylamine as phase transfer catalyst,benzyl cinnamate was synthesized directly under normal pressure and microwave irradiation.The effects of amount of catalyst,power and time of microwave irradiation on yield were studied.The most suitable reaction conditions were that with 0.05mol sodium cinnamate ,the mole ratio of sodium cinnamate and benzyl chloride was l.0:3.4,the amount of triethylamine was 2.5mL/0.05mol sodium cinnamate and the microwave irradiation time 11min with the power of 450W.The yield of benzyl cinnamate was over 82.5%.
