Cu(ii)Cl2 containing bispyridine-based porous organic polymer support prepared via alkyne–azide cycloaddition as a heterogeneous catalyst for oxidation of various olefins

Abstract

A new type of porous organic polymer (POP) based heterogeneous catalyst Cu-POP was prepared by immobilizing Cu(II)Cl₂ into bpy containing POP prepared via alkyne–azide cycloaddition. This new catalyst showed efficient catalytic activities and outstanding reusability. Remarkably, one batch of Cu-POP was continuously used for all olefins without losing its activity by simply washing.
