실험 절차

4-hydroxybenzophenone (186.7 g, 940 mmol, Fluka Chemical) was dissolved in 2-butanone (700 mL, Fisher Scientific) in a 2L four-necked flask equipped with a mechanical stirrer, reflux condenser, addition funnel and internal temperature probe. K2CO3 (195 g, 1.41 mol, Aldrich Chemical) was added to the reactor, and the contents was placed under a slow N2 purge. Allyl bromide (123 mL, 1.41 mol, Aldrich Chemical) was charged to the addition funnel. The pot temperature was raised to 65° C., at which point the allyl bromide was added over the course of 30 minutes. The reaction was stirred for 6.5 h at 65° C. after the addition was completed. At this point no starting material was present as determined by GC analysis.
