Immediate hydroxylation of arenes to phenols via V-containing all-silica ZSM-22 zeolite triggered non-radical mechanism

Abstract

Hydroxylation of arenes via activation of aromatic Csp2–H bond remains a challenge. Here, the authors have managed to get various arenes hydroxylated to corresponding phenols using stoichiometric hydrogen peroxide and a series of robust V–Si–ZSM-22 catalysts synthesized via an ionic liquid involved dry-gel-conversion route.
