regioselective transition-metal-free one-pot synthesis of arylsulfones via the reactive quinone imine ketal intermediate is demonstrated using easily accessible bench-stable sulfinate salts. A broad range of functionality on p-anisidine substrates as well as sulfinate salts was tolerated under mild reaction conditions to provide the corresponding arylsulfones in good to excellent yields.

A highly chemo- and regioselective approach for the construction of ortho-amino triarylphosphine oxides has been achieved through a C–P cross-coupling reaction involving quinoneimineketals (QIKs) with Ar2P(O)H and catalyzed via a Lewis base. This alternative protocol provided a wide substrate scope with excellent yields (82–95%), and a variety of ortho-amino triarylphosphines were obtained with high

Indoles, especially multisubstituted ones, are privileged scaffolds found widely in natural products, bioactive molecules, fine chemicals, and organic functional materials. Although several intramolecular electrochemical cyclization reactions of vinyl anilines to construct indoles have been reported in recent years, the intermolecular process between simple anilines and other readily available synthons
