Title: CHRYSOTILE-SUPPORTED TRANSITION-METAL SALTS AS FRIEDEL-CRAFTS CATALYSTS
Author: PINHO, RO

Abstract: Lewis acids (ZnCb, CoCl2, FeCl3, NiCl2, CrCl3) were immobilized on chrysotile( a fibrous asbestos-type magnesium silicate). The catalytic activity of these supported acids was studied by a Friedel-Crafts reaction of benzene and benzyl chloride to give diphenylmethane in 60 to 75% yields. The acylation reaction of anisole and acetyl chloride which was catalyzed by these supported acids gave para- and ortho-acetylanisole in a ratio of 70:30. These catalysts can be reused in further reactions without a significant reduction in the chemical yield of the products.
