Catalysis by topologically anchored metal complexes. Liquid-phase hydroxylation of benzene by H₂O₂ in the presence of zeolite-supported Fe(II) phthalocyanine

Abstract

Fe(II) phthalocyanine topologically anchored on NaA zeolite has been prepared. The catalytic activity of zeolite-supported Fe(II) phthalocyanine has been studied in the liquid-phase hydroxylation of benzene by H 2 O 2 . The main product of the reaction at room temperature is phenol. By refluxing, the reaction proceeds to give the products of subsequent oxidation, i.e., hydroquinone and p-benzoquinone, in low yields.Key words: topologically anchored Fe(II) phthalocyanine, catalysis, oxidation, benzene, phenol.
