采用闪光光解结合步进扫描和快速扫描傅里叶变换红外光谱研究了一种在金属配位层中具有三个额外羰基配体的皱状、准四方锥形铁环丁二烯[Fe{κ（2）-C3（NEt 2）3 }（CO）3 ] BF 4（[1] BF 4）的光化学.在室温下的液体溶液中，用λ=355 nm的光激发导致一个CO配体的损失，其从基底金属配位位点裂解。 在实验的时间分辨率内，溶剂分子迅速地重新填充在配位不饱和金属中心处产生的空位。在弱相互作用的液体二氯甲烷中，络合物的抗衡离子随后能够取代铁中心的配位层中的溶剂，从而形成作为稳定产物的含有四元铁杂环的中性二羰基四氟硼酸铁（0）物种。
Flash photolysis combined with step-scan and rapid-scan Fourier-transform infrared spectroscopy was carried out to explore the photochemistry of a puckered, quasi-square pyramidal ferracyclobutadiene, [Fe{κ(2) -C3 (NEt2 )3 }(CO)3 ]BF4 ([1]BF4 ), that features three additional carbonyl ligands in the metal coordination sphere. In liquid solution at room temperature, an excitation with λ=355 nm light resulted in the loss of one CO ligand, which is cleaved from a basal metal-coordination site. Within the time resolution of the experiment, a solvent molecule promptly refills the resultant vacancy at the coordinatively unsaturated metal center. In the weakly interacting liquid, dichloromethane, the counterion of the complex is subsequently able to substitute the solvent in the coordination sphere of the iron center, thereby forming as a stable product a neutral dicarbonyl tetrafluoroborato iron(0) species containing a four-membered ferracycle.
