This catalytic system promoted by dual ligand catalyst readily achieved the highly efficient alkenylation of alkyl aryl ethers, cyclic aryl ethers, and diphenyl oxides. Moreover, the methodology was employed for the late-stage modification of drug.

In this study, a single fluorescent probe (DPFP) containing a 1,8-naphthalimide dye and a homoallylamino group for imaging pH and formaldehyde (FA) has been developed that exhibits significant blue fluorescence (λ at 455 nm) under acidic pH conditions (pH < 7.0) and green fluorescence (λ at 555 nm) in the presence of FA, respectively. Furthermore, probe DPFP was successfully applied to image acidic lysosomes and exogenous or endogenous FA in living HeLa cells.

A simple and facile protocols for copper‐catalyzed regionselective C4 nitration and azidation of 1‐naphthylamines via remote C–H activation that use of pyridyl amide fragment as the removable directing group have been firstly developed. These reactions proceed under mild conditions without any additives, tolerate a wide variety of functional groups, and afford a wide range of products in good to excellent yields. Control experiments suggest that those C–H activation reactions are likely to proceed through a single‐electron‐transfer (SET) process.
