Here, an α-selective Csp3-H bond functionalization of primary aliphatic alcohols with 1,4-naphthoquinones yielded Csp2-Csp2 coupled products driven by blue-LED light under catalyst, metal, base, and reagent-free conditions. In this transformation, cleavage of three C-H bonds (two sp3-C-H, one sp2-C-H, and one O-H) and four new bonds formed, leading to fluorescent 2-acylated-1,4-naphthohydroquinones.
