The reactions of seven thiophenes with benzyne generated from diphenyliodonium-2-carboxylate (DPIC) under a standard set of conditions led among other products to the formation of alpha- and beta-naphthyl phenyl sulfides 2a and 2b from thiophene (1a)

The reaction of thiophene with six different benzyne precursors under benzyne-forming conditions was examined to determine if this heterocycle could enter into cycloaddition or other reactions with this intermediate. The most satisfactory system prov

Complete proton and carbon NMR assignments were made for five 2-(2-X-phenyl)thiophenes (X = NH2, NO2, COOH, Br), four 2,5-diphenylheterocycles (thiophene, furan and N-methyl- and N-phenylpyrrole) and N-phenylpyrrole using HETCOR, COSY, XCORFE and, in

Benzyne, generated from diphenyliodonium-2-carboxylate, reacts with varous thiophens by addition to the sulphur and β-carbon to give, after loss of an acetylene moiety, benzo[b]thiophens in low but reproducible yields.
