実験手順
Following the same procedure as Example 1, p-nitrophenol (34.8 grams), acrylic acid (27 grams), and an inhibitor, phenothiazine (0.02 grams) was added to the pressure reactor. The anhydrous hydrogen fluoride (110 grams) was added before the system was warmed. When the reaction temperature was attained, a pressure of 140 psig was noted, similar to previous reactions. Work-up was carried out as previous examples and the 6-Nitro-4-Chromanone was isolated and characterized.
