Separation of unsymmetrical diimines by liquid chromatography |
| abstract |
Novel unsymmetrical diimines containing a polar group are made by preparing a mixture of the unsymmetrical diimine and two symmetrical diimines, for example by reacting a dicarbonyl compound with two primary amines. The unsymmetrical diimine is then purified by liquid chromatography. The unsymmetrical diimines are useful as ligands in olefin polymerization catalysts. |
