A protocol for the visible light driven preparation of unsymmetrical (hetero)aryl selenides and tellurides is described herein. The method exploits the peculiar photoreactivity of arylazo sulfones that act as thermally stable, precursors of aryl radicals under both photocatalyst- and additive-free conditions. The method developed shows an impressive versatility (more than fifty compounds isolated).

A visible light-induced formation of Aryl-Phosphorous bonds starting from arylazo sulfones and triaryl (or trialkyl)phosphites in the absence of any photoredox catalyst and any additives was developed. This reaction showed a broad substrate scope and afforded (hetero)aryl phosphonates in good yields and in up to the gram scale.

We developed a photocatalyst-free and additive-free, visible light induced borylation reaction using arylazo sulfones as starting material. This protocol shows some advantages such as mild conditions, simple equipment, and wide substrate scope, which gives a complementary protocol for the preparation of arylboronates.
