| Preventing CO-Releasing Systems from Forming Precipitates and Tuning CO-Releasing Rate via Ligand Exchange Reaction | |
| 摘要: 采用3个含巯基基团的水溶性化合物（硫普罗宁、巯基乙胺和巯基甘油）来诱导二铁羰基化合物[Fe2（μ-SCH2CH （OH） CH2（OH））2（CO）6]（1）释放CO。为了解决在CO释放过程中形成沉淀的问题，研究了乙二胺四乙酸（EDTA）对分解产物的溶解作用。结果表明EDTA不仅可以成功地预防CO释放体系中沉淀的生成，还可以协同促进化合物1分解释放CO。虽然所选择的配体都含有巯基功能基团，但其对化合物1释放CO的促进作用不同，据此可用于CO释放速率的调控。 | |

| Abstract: In this work, three water-soluble compounds (tiopronin, cysteamine, and mercaptoglycerol) which contain a thiol group have been used to initiate CO-release from a diiron hexacarbonyl complex[Fe2(μ-SCH2CH(OH)CH2 (OH))2(CO)6] (1). To overcome forming precipitates during the CO-releasing process, we investigated using ethylenediaminetetraacetic acid (EDTA) as the agent to solubilize products derived from the decomposition. Our results suggest that EDTA not only successfully prevents the CO-releasing system from forming precipitates, but also synergistically facilitates the CO-release from complex 1. Despite the fact that the chosen ligands possess a thiol functional group, their behaviors in promoting the CO-release from complex 1 are rather different, which can be exploited to tune the CO-releasing rate in potential applications. | |
