在此，我们报告的制备和表征的铁（III）salalen配合物，与变化的配体取代基和骨干调查。六个新的配合物的制备和其特征在于元素分析，质谱和X-射线晶体学。这些配合物已被应用于外消旋丙交酯在环氧丙烷中的开环聚合（ROP）。发现Fe（1）Cl具有中等全同立构偏好（P-m = 0.75-0.80），并且在溶液中表现出良好的分子量控制（D = 1.02-1.18）。Fe（2-7）Cl对ROP也有一定的催化活性，其催化活性与配体结构有关。
Herein, we report the preparation and characterisation of iron(III) salalen complexes, with variation of ligand substituents and backbone investigated. Six new complexes were prepared and characterised by elemental analysis, mass spectrometry and X-ray crystallography. These complexes have been applied for the ring opening polymerisation (ROP) of rac-lactide in propylene oxide. Fe(1)Cl was found to have a moderate isotactic preference (P-m = 0.75-0.80) and demonstrated good molecular weight control in solution (D = 1.02-1.18). Fe(2-7)Cl were also active for ROP and activities could be related to ligand structure.
