| titleOfInvention | Novel bridged beta-diimido binuclear aluminum compound and preparation method and use thereof |
| abstract | The invention discloses a novel bridged beta-diketiminate homodinuclear aluminum compound, a preparation method thereof and application of the compound in polymerization of lactones. The preparation method is as follows: a bridged beta-diketiminate homodinuclear ligand compound and alkyl aluminum are reacted in an organic medium to give a homodinuclear aluminum complex for a bridged beta-diketminate ligand. The bridged beta-diketiminate homodinuclear aluminum compound is a high-efficiency catalyst which can be used for catalyzing the polymerization of lactones. The bridged beta-diketiminate homodinuclear aluminum compound has the advantages of producing polycaprolactone (Mw/Mn is between 1.4 and 2.3) with high and narrowly distributed molecular weight due to higher catalytic activities and meeting demands of industrial department, along with easily available raw materials, simple synthesis course, high product yield and stable properties. The structural formula of the compounded is shown above. |
