An efficient and convenient reaction system based on MnAl layered double oxide for the aerobic oxidation of alkylarenes

Abstract

An efficient and convenient catalytic system has been reported for the aerobic oxidation of alkylarenes based on Mn₂Al layered double oxide (Mn₂Al-LDO) without any additives. The heterogeneous catalytic system could tolerate various alkylarenes with satisfactory yields. The results demonstrated that Mn species in Mn₂Al-LDO are the catalytically active sites, and both HAT (hydrogen atom transfer) and ET/PT (electron transfer/proton transfer) processes were suggested to be ascribed for the transformation. A possible reaction mechanism has been proposed based on a series of control experiments.
