Cycloalkanes oxidation with O2 catalyzed by a novel metalloporphyrin-based covalent coupling structure with bimetallic catalytic centers through synergistic mode
A novel bimetallic central covalent coupling catalytic system (Porp.Co@Zn-C6) based on Tris(4-Cl)(4-OH)Co and Tris(4-Cl)(4-OH)Zn was established to improve cycloalkanes oxidation. In particular, the partially-oxidized product's selectivity rose from 86.4% to 97.5% and the cyclohexane conversion was boosted from 3.80% to 4.41%. Simultaneously achieved improvements in conversion and selectivity. In this system, Co(II) was employed to activate molecular oxygen, Zn(II) was utilized to strengthen the utilization of cyclohexyl hydroperoxide and to be avoided its thermal decomposition in disorder state. This proposal can be very suitable for other cycloalkanes as well, which will improve the conversion and selectivity concurrently.
