실험 절차

Cinnamylidene acetyl chloride was prepared by stirring approximately 17.15 gms of cinnamylidene acetic acid with 30 ml thionyl chloride in 300 ml of petroleum ether for 12 hours at room temperature. The reaction mixture was then refluxed for 4 hours in an oil bath at a temperature of approximately 40 to 50° C. The excess thionyl chloride and the petroleum ether were removed under reduced pressure. 1HNMR: 3=6.2 ppm (d, 2H), δ=6.9 ppm (q, 2H), δ=7.5 ppm (m, 5H). UV (in dichloromethane): λmax=333 nm, λmin=256 nm.
