Procedure

0.5 Gm. of phosphorus pentachloride is added to a solution of 0.5 gm. of 2-(2-propenyl)5H-dibenzo[a,d]cyclohepten-5-one in 20 ml. of benzene, and the mixture is stirred for one hour, and then added to a mixture of 1.0 ml. of ethylene glycol, 1.0 ml. of triethylamine and 20 ml. of acetonitrile. After 2 hours the mixture is washed with water, dried and evaporated to give a nearly quantitative yield of 5,5-ethylenedioxy-2-(2-propenyl)5H-dibenzo[a,d] cycloheptene.
