Preparation of a zeolite X-encapsulated copper(ii) chloride complex and its catalysis for liquid-phase oxygenation of enamines in the presence of molecular oxygen

Abstract

Copper(II) chloride complexes were readily prepared within pores of zeolite X with the modified zeolite found to act as a heterogeneous catalyst for the oxygenation of a variety of enamines in the presence of molecular oxygen without leaching of the active copper species.
