A metal-free visible-light-induced regioselective ortho-C—H phosphonylation of β-naphthols with diarylphosphine oxides has been developed using fluorescein as an organophotoredox catalyst in the presence of K2S2O8 at room temperature under N2 atmosphere. This feature along with mild reaction conditions, sensitive functional group tolerance, good to excellent yields, high regioselectivity, and scale-up synthesis makes it an ideal and practical alternative modification of β-naphthols. The experimental result suggests that a radical pathway is involved in the reaction.

Key words: β-naphthols, diarylphosphine oxide, visible-light catalysis, phosphonylation, radical reaction
