The synthesis and properties of ferroceno[1′,2′;1″,2″]bis(1,3-dithiol-2-thione and -2-one) derivatives

Ferrocene, t-Bu- and 1.1′-bis(t-Bu)ferrocenes fused with 1,3-dithiol-2-thione ring were prepared. In spite of the presence or absence of t-Bu groups, the 1,3-dithiol-2-thione rings are heaped on top of each other. In the anodic scan, the 1,3-dithiol-2-thione part is oxidized likely to cause a coupling of the S atoms.
