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
在这里,在催化剂、金属、碱和无试剂条件下,脂肪伯醇与 1,4-萘醌的 α-选择性 C sp3 -H 键官能化产生了由蓝色 LED 光驱动的 C sp 2 -C sp 2偶联产物. 在该转化过程中,三个 C-H 键(两个 sp 3 -CH、一个 sp 2 -C-H 和一个 O-H)断裂并形成四个新键,从而产生荧光 2-acylated-1,4-naphthohydroquinones .
