首次制备了一种新型二氰甲基自由基，通过苯连接剂与二茂铁偶联作为给电子单元。该自由基与溶液中的σ-二聚体处于平衡状态，并通过x射线单晶结构分析证实了其结构。由于单体/二聚体平衡，该自由基表现出独特的电化学氧化还原行为，这取决于温度和扫描速率。
A novel dicyanomethyl radical conjugated with ferrocene as an electron donating unit through a benzene linker is prepared for the first time. This radical is in equilibrium with the σ-dimer in solution, and the structure of the σ-dimer was confirmed by X-ray single crystal structure analysis. Due to the monomer/dimer equilibrium, this radical showed unique electrochemical redox behaviour depending on the temperature and scan rate.
