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

Abstract We report a stable and porous 3D covalent-porphyrinic framework CPF-2, which is easily post-metalated with different metal ions to tune the catalytic properties. The cobalt(II) metalated material Co-CPF-2 exhibits high efficiency in heterogeneous catalysis of the aerobic epoxidation of olefins under mild conditions, in which > 99% conversion, 93% epoxide selectivity, 29,215 turnover number (TON) and 3434 h − 1 turnover frequency (TOF) have been realized for the aerobic epoxidation of styrene.
