Abstract

Abstract: Invited for the cover of this issue is the group of Hayato Tsurugi and Kazushi Mashima at the University of Osaka. The image depicts a cerium complex with a dianionic pentadentate ligand acting as a catalyst for aerobic oxidation of arylmethanols, in which a dinuclear cerium(IV) side‐on peroxo complex is the key intermediate. The corresponding trivalent complex was able to activate dioxygen, and the oxidation proceeded catalytically under atmospheric pressure with inexpensive and environmentally friendly dioxygen as the primary oxidant.

Abstract : " Thus, our big surprise was that the dioxygen dicerium complex worked as a catalyst for producing arylaldehydes from the corresponding alcohols, and the redox chemistry of Ce III /Ce IV was closely related to the catalyst performance of the Cu I /Cu II system ."
