Reaction Steps

A mixture of 16.8 grams (0.1 mole) dibenzofuran and 39.2 grams (0.1 mole) phenyliodoso tosylate in 150 ml glacial acetic acid was stirred for 3.5 hours at 50° C. There was added to the mixture, 200 ml diethyl ether which resulted in the precipitation of 3-dibenzofuranyl phenyl iodonium tosylate. The mixture was suspended in water to remove unreacted phenyliodoso tosylate then filtered and dried. A 62.5% yield of the above salt was obtained having a melting point of 188°-190° C.
