摘要： 以二茂铁苯甲酰氯和二茂铁间(对)苯胺为原料,合成了两个新的双二茂铁硫脲衍生物FcL1和FcL2.通过IR,1HNMR和元素分析等手段确定了标题化合物的结构.X射线单晶结构分析表明,FcL1属于三斜晶系,P1空间群,R1=0.0786,wR=0.1762.电化学分析结果表明,FcL1和FcL2的电化学性质相似,说明化合物中的两个二茂铁基所处的化学环境基本相同.间苯胺取代和对苯胺取代对化合物在电极表面的扩散系数影响不大,但对其反应速率常数则有较大的影响.

Abstract: Two novel diferrocenyl thiourea derivatives FcL1 and FcL2 were synthesized. The structures of the compounds were determined by elemental analysis, IR and 1H NMR spectra. The X-ray single crystal structure analysis of FcL1 indicates that the crystal belongs to triclinic system, P1 space group, there was a hydrogen bond in the compound. It was found that the electrochemical property of FcL1 was very similar with that of FcL2, the redox couple(FcL1: E1/2=600 mV; FcL2: E1/2=605 mV) was corresponding to the progress of 2Fc3++2e-2Fc2+, which can be rationalized by the equivalent environment of the ferrocene subunit in each case. The difference between m-ferrocenylaniline and p-ferrocenylaniline didn't cause the distinct change for their diffusion coefficient(D), but caused the distinct change for their electrochemical reaction rate constant(ks).
