Cu-Catalyzed C(sp3)–H Bond Activation Reaction for Direct Preparation of Cycloallyl Esters from Cycloalkanes and Aromatic Aldehydes

Cu-catalyzed dehydrogenation–olefination and esterification of C(sp3)–H bonds of cycloalkanes with TBHP as an oxidant has been developed. The reaction involves four C–H bond activations and gives cycloallyl ester products directly from cycloalkanes and aromatic aldehydes.
