A vanadyl complex grafted to periodic mesoporous organosilica: a green catalyst for selective hydroxylation of benzene to phenol

Angew Chem Int Ed Engl. 2012 Jul 27;51(31):7756-61. doi: 10.1002/anie.201203275. Epub 2012 Jun 22.

Abstract

Selective benzene hydroxylation: A periodic mesoporous organosilica embedded with a vanadyl(IV) acetylacetonate complex has been synthesized through a co-condensation method. This system is a catalyst for direct hydroxylation of benzene to phenol, presenting a selectivity of 100 % towards the phenol formation as well as an excellent catalytic recyclability (see scheme).
