Oligonuclear ferrocene derivatives containing either sulfur or disulfur bridges were obtained by three methods **: 1.) The reaction of 1,1′-dilithioferrocene, fcLi 2, with diferrocenyldisulfane, Fc-SS-Fc ( 1a), can be used to prepare trinuclear 1,1′-bis(ferrocenylthiolato)ferrocene, Fc-S-Fc-S-Fc ( 9a); the selenium-and tellurium-bridged complexes Fc-E-fc-E-Fc (E = Se ( 9b), Te ( 9c)) are accessible in an analogous manner. 2.) 1,2,3-Trithia[3]ferrocenophane, fc(S 3), reacts with organolithium compounds, RLi, to give (after air oxidation) bis(1′-organylthiolato-ferrocenyl)disulfanes, RS-fc-SS-fc-SR (R = nbutyl ( 11a) and phenyl ( 12a)); in the case of lithioferrocene (R = Fc) a tetranuclear product, FcS-fc-SS-fc-SFc ( 13a), is formed. 3.) Radical-initiated (AIBN) reactions of 1,1′-ferrocenedithiol, fc(SH) 2, often lead to oligonuclear ferrocene derivatives containing disulfur bridges. The AIBN induced reaction between fc(SH) 2 and ferrocenethiol, FcSH, gives yellow products the majority of which are insoluble in organic solvents. The fraction soluble in hexane/ethylacetate (10:1) contained small amounts of Fc-SS-Fc ( 1a) and Fc-SS-fc-SS-Fc ( 15a). The AIBN induced reaction of fc(SH) 2 with norbornadiene (1:1) gives oligomers C 7H 9S-fc-S-[S-fc-S] n − 2-S-fc-SC 7H 9 ( 16a) in which the chain consists of disulfur-bridged 1,1′-ferrocenylene units and the end groups are either 3-nortricyclyl or 5- exo-norborn-2-enyl substituents. Oligomers with a chain length of n = 2–12 were observed by gel permeation chromatography (GPC), the average number ( n ) of ferrocene building blocks being close to n = 3. The new compounds were identified by their EI mass spectra and characterized by their 13C NMR spectra.
