Metalloporphyrinic framework containing multiple pores for highly efficient and selective epoxidation.

ABSTRACT

Metalloporphyrin Mn(III)Cl-5,10,15,20-tetrakis(3,5-biscarboxylphenyl)porphyrin, having eight carboxylate groups in multiple coordination modes, connects with paddle-wheel Zn2(COO)4 units for the construction of an interesting porous porphyrinic framework that demonstrates high efficiency and stability upon epoxidation of olefins with excellent substrate size selectivity.
