CSIC ORCID | Fecha de publicación: | 10-abr-2019 | Editor: | Royal Society of Chemistry (UK) | Citación: | Dalton Transactions 48: 6435-6444 (2019) | Resumen: | New aluminium-alkali metal heterometallic compounds using the bulky ligand OAr = 2,6-bis(diphenylmethyl)-4-tert-butylphenoxide have been synthesized and characterized. The species obtained, [MAlMe (OAr)] (M = Li(2a), Na(2b), K(2c)) and [MAlMe (OAr) ] (M = Li(3a), Na(3b), K(3c)), include some of the few heterobimetallic examples of aluminate complexes with O-donor ligands described so far. Their activity in polymerization towards a difunctional monomer, such as Glycidyl Methacrylate (GMA), was evaluated. The compounds were revealed to be able to polymerize the acrylate groups via vinyl polymerization. Interestingly, the homometallic counterparts [AlXMe(OAr)] (X = Cl, Me), previously described by us, are very active in ROP processes of GMA. The combined polymerization process using both catalysts has also been explored to obtain a polymeric material with an exciting macromolecular architecture. | Descripción: | 10 pags., 5 figs., 3 tabs. | Versión del editor: | http://dx.doi.org/10.1039/c9dt00761j | URI: | http://hdl.handle.net/10261/208582 | DOI: | 10.1039/c9dt00761j | Identificadores: | doi: 10.1039/c9dt00761j issn: 1477-9234 |
