Abstract
A method of: reacting a dihydroxybenzene with bromine to form a bromodihydroxybenzene; reacting the bromodihydroxybenzene with trifluoromethanesulfonyl chloride or trifluoromethanesulfonic anhydride to form a bromotrifluoromethanesulfonatobenzene; and reacting the bromotrifluoromethanesulfonatobenzene with phenylacetylene to form a phenylethynylbenzene.
