反応手順
9,10-Dihydro-9,10-ethanoanthracene-11-methanol (2 gm) was combined with triphenylphosphine dibromide (5.3 gm) in carbon tetrachloride (60 ml). The mixture was heated to reflux 1 hour, filtered, and the filtrate was concentrated on a rotary evaporator. The residue was boiled in n-heptane (75 ml), filtered hot, and the filtrate cooled. The white precipitate was filtered and air dried to provide the product (mp=103-106° C.).
