Molecular sieves of the MCM-41 type were studied as catalysts for the Friedel-Crafts acylation of 2-methoxynaphthalene in the liquid phase. When MCM-41 in the H+ form is used as Bronsted-acid catalyst, acylation with acetic anhydride gives substitution predominantly at the l-position. Increased reac
A new hybrid catalyst affording polymerization of phenylacetylene (PhA) into high-molecular-weight (M w = 180 000) high-cis-polyphenylacetylene (PPhA) was prepared via immobilization of [Rh(cod)Cl] 2 (cod = 4 -cycloocta-1,5-diene) on siliceous mesoporous molecular sieves MCM-41 modified by 3-aminopr
