ACC-Oxidase like activity of a copper (II)-ACC complex in the presence of hydrogen peroxide. Detection of a reaction intermediate at low temperature.
A Cu(II)-ACC complex [(Bpy)Cu(ACC)(H2O)]ClO4 (1) was prepared and its treatment with hydrogen peroxide gave rise to ethylene production in an ACC-Oxidase like activity. A brown species that could be a key intermediate in the reaction was detected at low temperature.
