Understanding of the low temperature auto-oxidation scheme of sec-alcohols based on a Cu(II)-MOF with open metal sites.

A Cu(II)-MOF (1') with open metal sites was readily obtained by removing the coordinated water molecule at 120 °C. It can be used as a probe to evidence the sec-alkyl hydroperoxide species generated from room temperature sec-alcohol auto-oxidation in air. The formed alkyl hydroperoxides can be effectively catalyzed by 1' to decompose into molecular oxygen and corresponding sec-alcohols under ambient conditions.
