Synthesis and electrochemical properties of ferrocene-containing N-allylcarbamates: Structure of CH2CHCH2–NHCOO–CH2Fc
摘要:
A series of ferrocene-containing N-allylcarbamates, CH2=-CHCH2-NHCOO-(CH2)(m)Fc with m = 1-4 and Fc = ferrocenyl, was synthesized by reacting allylisocyanate with different ferrocenylalcohols, Fc-(CH2)(n)-OH (n = 1-4). The electrochemistry of the carbamates was studied by cyclic voltammetry in CH2- Cl-2/0.1 M (NBu4PF6)-Bu-n utilising a glassy carbon working electrode. The ferrocenyl group showed reversible electrochemistry with the formal reduction potential (E degrees' versus FcH/FcH(+)) of the ferrocenyl group inversely proportional to spacer chain length. The single crystal X-ray structure of the complex with m = 1 (monoclinic, P2(1)/c space group) explained the good through bond communication that was electrochemically detected between the electron-withdrawing NHCOO group and electron-donating Fc modalities.

mainly located on the sulfur. Rapid exothermic dimerization leads to the observed dimers, Fc(CH2)n–S–S–(CH 2)nFc. Reduction of the ferrocenium groups on the dimer occurs at potentials that still showed the ferrocenyl group ΔE = Epa,monomer – Epc,dimer ≤ 78 mV, indicating that the redox properties of the ferrocenyl group on the mercaptans are very similar to those of the dimer. 1H NMR measurements showed

ferrocene-based molecules coined ferrocifens, owing to its unique redox properties. The addition of imide entities to the historical ferrociphenol scaffold tremendously enhanced the cytotoxic activity of a large panel of cancer cell cultures and preliminary studies showed that the reduction of one of the carbonyl groups of the imide groups to the corresponding α-hydroxylactams only slightly affected the antiproliferative
