| 摘要: 采用谱学和X射线单晶衍射技术,分别对四苯基铁杂环戊二烯羰基铁配合物(μ2, η4-C4Ph4)Fe2(CO)6(1)和四苯基取代环戊二烯酮(Ph4C4CO)(2)的晶体结构进行了分析和表征。在太阳光和氙灯光(带有4种滤光片)的照射下,利用红外吸收光谱,详细地考察了配合物1的光分解过程和分解产物。实验结果表明,配合物1的光分解速率与光源和波长有关,太阳光的光解速率最快;在同一氙灯光源下,全波长滤光片(320~780 nm)的光解速率最快。本文还对配合物1的热分解和溴分解反应进行了对比研究,结果证实,3种分解反应的主要产物均为配体2。 | |

| Abstract: The crystal structures of hexa-carbonyl-di-iron complex with ferratetraphenyl cyclopentadiene ring (μ2, η4-C4Ph4)Fe2(CO)6 (1) and tetraphenyl substituted cyclopentadienone ligand (Ph4C4CO) (2) were characterized by spectroscopic determination and X-ray single crystal diffraction technique. The decomposition products and process of ferrole complex 1 were studied by FTIR, using sun light and xenon lamp with four filters as light source, respectively. The results show the light decomposition rate of ferrole complex 1 relates to light source and wavelength. The decomposition rate of sun light source is the fastest, and the decomposition rate of whole wavelength (320~780 nm) is correspondingly faster than that of other wavelengths under irradiation of the same xenon lamp. Ligand 2 is the main product from three decomposition reactions of ferrole complex 1 in the presence of light, heat and Br2 in acetic acid, respectively. | |
