By adopting the interplay between ligand-enabled Au(I)/Au(III) catalysis and the unique π-activation mode of gold complexes, a highly coveted 1,2-heteroarylation of alkenes has been accomplished. The present ligand-enabled approach not only circumvents the requirement for strong sacrificial oxidants or photocatalysts but also operates under mild reaction conditions by utilizing simple and non-prefunctionalized

Seleniranium ions at low temperatures (-90 to -78 degrees C) will initiate effective Friedel-Crafts cyclization if a suitably placed arene is allowed to react even when the arene is unactivated. These intermediates generated from N-aryl-N-tosylamides undergo a novel, surprisingly efficient, detosylative cyclization to form 5- or 6-membered nitrogen heterocycles. A debenzylation route is preferred if both benzyl and tosyl groups are present in the substrate.
