Visible light photoredox-catalyzed phosphorylation of α-bromostyrenes: a mild synthesis of β-ketophosphine oxides

Abstract

Visible light-mediated photocatalytic phosphorylation of α-bromostyrenes is described. The β-ketophosphine oxide derivatives were conveniently synthesized from α-bromostyrene derivatives, which are useful synthetic intermediates, using an inexpensive organic photocatalyst, Eosin Y.
