Synthesis and post-metalation of a covalent-porphyrinic framework for highly efficient aerobic epoxidation of olefins

A stable and porous covalent-metalloporphyrinic framework Co-CPF-2 exhibits high efficiency in heterogeneously catalyzing the epoxidation of olefins under mild aerobic conditions, in which > 99% conversion, 93% epoxide selectivity, 29,215 turnover number and 3434 h− 1 turnover frequency have been realized for the epoxidation of styrene.121
