Direct CHamidation of arylphosphoryl compounds has been developed by using an IrIII catalyst system under mild conditions. A wide range of substrates could be employed with high functional‐group tolerance. This procedure was successfully applied for the first time to the asymmetric reaction giving rise to a P‐chirogenic center with a high diastereomeric ratio of up to 19:1 (90 % de).

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
