反応手順
180 mg of 4'-vinyl, 4-biphenyl aldehyde was mixed with 0.3 ml of 2-hydroxyacetophenone in 30 ml of ethanol. In a separate flask, 2.0 gms of NaOH was dissolved in 10 ml of aq. ethyl alcohol (50%). An NaOH solution was slowly added to the aldehyde solution. The resulting solution slowly changed its color from green to yellow to dark red. The rest of the reaction was carried out according to the method described in Example 1(b) above, producing 4'styryl, 3-hydroxyflavone.
