Kaolin-assisted Aromatic Chlorination and Bromination

Abstract

Moist kaolin catalyses the regioselective and high-yielding chlorination and bromination of C₆H₅OR (R=C₁–C₈ alkyl, Bu^t, allyl, cyclohexyl, benzyl) to 4-XC₆H₄OR (X=Cl and Br, respectively) with NaClO₂ and Mn(acac)₃ in CH₂Cl₂ in the absence and presence of NaBr, respectively, under mild and neutral conditions.
