英文摘要 | A series of N,N'-bidentate iron(II) complexes (Fe1-Fe5) bearing 4-arylimino-1,2,3-trihydroacridines were prepared by one pot reaction of 2,3-dihydroacridin-4-one, corresponding anilines and FeCl2 center dot 4H(2)O. All these complexes were characterized by FT-IR spectroscopy and elemental analysis, while single crystal of Fe5 was the interest for X-ray analysis, revealed tetrahedral geometry around iron center. In the presence of tetradecanol, the catalysts system Fe1-Fe5/2LiCH(2)SiMe(3) exhibited high efficiency toward ring opening polymerization of epsilon-CL at room temperature; a rare example of iron(II) complexes for ROP of cyclic ester at such lower temperature compared to common efficient iron(III) precatalysts. The H-1 NMR spectra and MALDI-TOF analysis of the resultant PCL displayed as an evident for linear structure capped with tetradecylalkoxy. Therefore, polymerization proceeded through coordination-insertion mechanism in which the iron(II) alkoxide generated in situ acted as the active species. |
