A copper-catalyzed approach for the synthesis of 1-acyloxy-2,2,6,6-tetramethylpiperidines through the C–C bond cleavage of cyclic or acyclic ketones was developed. In this chemistry, a combination of CuCl2·2H2O, 1,10-phenanthroline monohydrate, and aniline was crucial for the formation of the desired products by the reaction of ketones with TEMPO. This research provides a new strategy for the further transformation of α-aryl cyclic or acyclic ketones.

A novel tert-butyl hydroperoxide (TBHP)-promoted oxidative C=C double-bond cleavage of enamines is described. Heating a solution of an electron-deficient enamine in chlorobenzene at 80 °C in the presence of TBHP for two hours led to cleavage of the C=C bond. This study offers a new strategy to carry out C=O double-bond formation by the use of TBHP.
