资源简介：
A series of new unsymmetrical 1,1‘-disubstituted ferrocenediyl ligands featuring thioether substituents (SR, SR‘ where R ≠ R‘: Me, Ph, tBu) have been conveniently synthesized via cleavage of ferrocenylsulfanes. The ligands display a range of coordination chemisty, exemplified by reaction with Pt, Pd, and W metal centers, and structural characterization indicates the bidentate, chelating nature of the ligands. Electrochemical studies show that the diferrocenyldisulfanes exhibit two separated one-electron oxidations where the mixed-valent monocations belong to the partially delocalized Robin-Day Class II, while for the metallocenophanes, chemical reversibility is noted along with some decomposition over time.
