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 H2O2. 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.
