Procedure

To 17 ml. of well stirred trifluoroacetic acid, 0.16 g. of 4-(p-fluorophenyl)-4-hydroxycyclohexanone (obtained as in Example 3) is added. At the end of about 5 minutes the mixture is poured into an excess of aqueous sodium bicarbonate solution. The solid material is collected on a filter and recrystallized from petroleum ether to give a 96% yield of 4-(p-fluorophenyl)-3-cyclohexen-1-one melting at 44.5° to 46.5° C.
