Inside Back Cover: Cu(II)‐Catalyzed Ligand‐Free Oxidation of Diarylmethanes and Second Alcohols in Water (Chin. J. Chem. 9/2017)

The inside back cover picture shows a simple and efficient Cu(II )‐catalyzed ligand‐free oxidation of diarylmethanes and secondary alcohols using 70% TBHP in water. A series of diarylmethanes were directly oxidized into diaryl ketones in 67%–98% yields. Additionally, various secondary alcohols were also transformed into the desired products in 48%–98% yields. Importantly, the catalytic system in the absence of any organic solvent, surfactant, or phase transfer agent, had a wide substrate scope and a high tolerance for various functional groups. More details are discussed in the article by Liu et al. on page 1391–1395.
