Un nouveau type de ferrocénophane, premier exemple de structure dimère

Ferrocene: An unrivaled electroactive building block for the design of push-pull dyes with near-infrared and infrared absorptions

“…This instability is notably the result of their facile reduction, notably for titanocenes. To improve their stability, an effective strategy consists in introducing heteroatoms such as oxygen, selenium or sulfur [168][169][170][171][172][173][174]. On this basis, a series of Zr and Ti-based metallocenes bearing ferrocene substitutes were examined for the spectroelectrochemical properties [175].…”

Synthesis and Electrochemical Behavior of Ferrocenyl‐Functionalized Metallocenes M(η5‐C5H5)2(EFc)2 (M = Ti, Zr; E = O, S, Se)

“…In contrast, less is known about ferrocenyl(alkyl)oxy, ferrocenylsulfanyl‐ and ferrocenylselanyl‐substituted metallocenes . For example, electrochemical studies on fc(µ 2 ‐ S 2 )(µ 2 ‐ S)[Ti] (fc = Fe(η 5 ‐ C 5 H 4 ) 2 , [Ti] = Ti(η 5 ‐ C 5 H 5 ) 2 ) were carried out displaying decomposition of this complex after initial ferrocene/ferrocenium oxidation resulting in a new unidentified species with a reversible process in the range for ferrocenyl groups …”

Synthesis and reactivity of cyclopentadienyl ruthenium complexes containing ferrocenylselenolates

“…Ferrocenylselenolate complexes can be prepared by the metathesis reaction of an alkali metal-selenolate salt [8][9][10][11][12][13], via chalcogenolysis cleavage of a Se-H bond [14,15] or by oxidative addition of diferrocenyldiselenide [16][17][18][19], as well as by reactions between trimethylsilyl(ferrocenyl)selenides and metals with a suitable leaving group such as a halide or an acetate ligand [20][21][22].…”
