The direct air-oxidation strategy enables the transformation of arylphosphine oxides into phosphinoyl radicals, which are subsequently used in the synthesis of benzo[b]phosphole oxides by combining with various alkynes.

A visible-light enabled, chemoselective photoreduction of 1,2-dicarbonyl compounds by using Hünig's base as reductant is reported.

The wavelength-regulated, photoredox-catalyzed stereodivergent synthesis of (Z)- and (E)-1,4-enediones from phosphonium ylides is reported.
