Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Pan, HF; Li, YF; Wang, YL; Ge, Y; Xia, SW; Li, YH. The CAS is 100-51-6. Through research, I have a further understanding and discovery of Benzyl Alcohol
A series of aluminum complexes based on a beta-diketiminate ligand HL (HL = N{-4-[(2,6-diisopropylphenylamino)pent-3-en-2-ylidene]-6-methyl}pyridin-2- amine) have been prepared and characterized spectroscopically and structurally. Reactions of the HL ligand with one equivalent of AlMe3, AlEt3 and AlEt2Cl, respectively, in toluene, gave complexes [LAlMed(2)] (1), [LAlEt2] (2) and [LAlEtCl] (3) in high yields. Complexes 1 and 2 contain four-coordinated mononuclear aluminum center. The aluminum center of 3 is five-coordinated. Complexes 1-3 were used to catalyze the ring-opening polymerization of epsilon-caprolactone. Complexes 1-3 are very rare cases of aluminum alkyl compounds supported by beta-diketiminate ligands, which show moderate activity toward the ring-opening polymerization (ROP) of epsilon-caprolactone (CL) in the absence of benzyl alcohol. However, in the presence of benzyl alcohol, the polymerization rate is remarkably accelerated and the conversions are greatly improved. The monomer conversion and number average molecular weight of poly(epsilon-caprolactone) (PCL) catalyzed by 1-3 shows a linear relationship. This result indicates that the polymerizations mediated by 1-3 exhibited controllable manner. (C) 2019 Elsevier Ltd. All rights reserved.
