Syntheses aud Electrochemical Studies of Derivatives of Ferrocene (Ⅰ) Cyclic Voltammetric Studies of Derivatives of Ferrocene
【摘要】 应用循环伏安法研究了甲酰基二茂铁、乙酰基二茂铁和1,1′-二乙酰基二茂铁在高氯酸钠的乙醇浴液中和Pt电极上的电化学行为。用循环伏安法理论分析实验结果表明,上述二茂铁衍生物发生了准可逆的电荷转移反应,得出了相应的电荷转移反应传递系数α和电极反应速率常数K_?。讨他了有关取代基对电极过程动力学参数的影响。
【Abstract】 The electrochemical behavior of derivatives of ferrocene on platinum electrodewas investigated by cyclic voltammetry measurements in solution of ethanol containingNaClO4 as supporting electrolyte. It was revealed that the reactions werequasi-reversible. FeX-FeX+ +e for three different deriratives of ferrocene containing thesubstituent chains-formyl. or-acetyl, or-1, 1’-acetyl group respectively. Theelectrochemical kinetics parameters （α and Ks） are calculated form the resultsobtained. The influences of the substituted groups on the kinetic parameters of electrodeprocesses are discussed for the investigated compounds.
