Trifluoromethanesulfonic acid → HCID 22269447, compound

Participants

Reaction Steps

To a mixture of 35.3 grams of 2,5-bis(5,6,7,8-tetrahydronaphthalen-2-ylmethyl)terephthalic acid and 4,6-bis(5,6,7,8-tetrahydronaphthalen-2-ylmethyl)isophthalic acid was added 120 grams of trifluoromethanesulfonic acid. The resulting mixture was stirred at room temperature for one hour followed by heating to 60° C. for six hours. The mixture was poured over 500 grams of ice. The resulting solid was isolated by filtration and washed with 500 mL of saturated aqueous sodium bicarbonate solution and then 4 L of water until the filtrate was neutral to pH paper. The solid was dried to give a mixture of 1,2,3,4,8,10,11,12,13,17-decahydroheptacen-6,15-dione and 1,2,3,4,10,11,12,13-octahydroheptacen-6,8(15H,17H)-dione
