Abstract

Highly efficient and selective carbon-carbon double bond aerobic cleavage of olefins catalyzed by metalloporphyrins was investigated, and carbonyl compounds and epoxide were produced as the main products. CoTPP (cobalt meso-tetraphenyl porphyrin) showed excellent activity for the oxidative cleavage of carbon-carbon double bond by using styrene as model compound, in which the TOF (turnover frequency) and selectivity toward benzaldehyde was obtained with 2×104 h−1 and 86%, respectively.
