Procedure

2-phenylfuran was prepared by the method of Example 32C from 2-bromofuran (0.93 g, 6.3 mmol), sodium carbonate (18 ml of 2 M aqueous solution), phenyl boric acid (0.93 g, 7.6 mmol) and tetrakis (triphenylphosphine) palladium (0) (0.36 g, 0.32 mmol). Flash chromatography with hexane provided 0.79 g (87% yield) of a colorless liquid.
