One-Pot Conversion of Cyclohexane to Adipic Acid Using a mu(4)-Oxido-Copper Cluster as Catalyst Together with Hydrogen Peroxide

摘要

The production of nylon-6.6 is one of the largest scale syntheses in industrial chemistry. The standard procedure is based on an energy consuming low-level conversion of cyclohexane to yield adipic acid in two steps that is converted to nylon-6.6 in a separate step. Therefore, there is a strong intent to optimize the synthetic route in an economic and ecologic matter. In this work, we present a one-pot oxygenation of cyclohexane with hydrogen peroxide and a mu(4)-oxido-copper cluster catalyst to yield dicarboxylic acids with adipic acid as the main product.
