[Rh(cod)Cl]2 Complex Immobilized on Mesoporous Molecular Sieves MCM-41 ů A New Hybrid Catalyst for Polymerization of Phenylacetylene.
Original language description
New hybrid catalyst affording polymerization of phenylacetylene into high-molecular- weight (Mw = 180 000) high-cis polyphenylacetylene (PPhA) was prepared via immobilization of [Rh(cod)Cl]2 (cod = .eta.4-cycloocta-1,5-diene) on siliceous mesoporous molecular sieves MCM-41 modified by 3-aminopropyltrimethoxysilane. The polymerization proceeds in catalyst channels and PPhA formed is continuously released into the liquid phase, from which it can be easily isolated. In comparison with related homogeneous catalysts, the hybrid catalyst provides comparable or even higher PPhA yields, considerably higher molecular weight of PPhA and reduced amounts of oligomeric by-products. Catalyst is resistant to Rh leaching; however, chemical transformation of anchored Rh species occurring during polymerization strongly reduces a possibility of catalyst re-using.
