WebMar 15, 2024 · In 2013, Kobayashi group [40] reported a hydrophosphinylation reaction of unactivated alkenes with secondary phosphine oxides (SPOs) by visible light-mediated photoredox catalysis (Scheme 4a). The reaction is performed under very mild conditions by using cheap organic dye (Rhodamine B) as the photoredox catalyst.
