Procedure
To a solution of 0.1 ml. of boron fluoride etherate in 100 ml. of anhydrous toluene is added 500 mg. of 1',5'-dichloro-dispiro[oxirane-2,9'(10'H)-anthracene-10',2"oxirane]. The mixture is stirred at room temperature for 6 hours and filtered. The filtrate is washed twice with 10 ml. portions of a mixture of 10 ml. of saturated sodium bicarbonate and 10 ml. of ice water, dried over anhydrous sodium sulfate and filtered. The toluene is removed by water pump evacuation at 30° C. to give 0.5 g. of the desired product as a pale yellow solid, mp. 160°-172° C.
