Design and Application of New Imidazolylsulfonate-Based Benzyne Precursor: An Efficient Triflate Alternative. — Sulfonylimidazole-based benzyne precursors are utilized in the reactions with azides to form benzotriazoles, with tosyl hydrazone to form indazoles, with β-ketoesters to form acyl alkylation products or with furans or pyr-roles to form bridged compounds. Mixtures of regioisomers are obtained when mono-substituted benzyne precursors are applied [cf. (XII)]. — (KOVACS, S.; CSINCSI, A. I.; NAGY, T. Z.; BOROS, S.; TIMARI, G.; NOVAK*, Z.; Org.
