Novel mixed-metal alkoxide clusters of lanthanide and sodium: Synthesis and extremely active catalysts for the polymerization of epsilon-caprolactone and trimethylene carbonate
Novel mixed-metal alkoxide clusters of lanthanide and sodium [Ln(2)Na(8)(OCH2CH2NMe2)(12)(OH)(2)], which were synthesized in reproducible high yields and structurally characterized, were found to be extremely active catalysts for the ring-opening polymerization of E-caprolactone and trimethylene carbonate.
