Thiol–yne chemistry of diferrocenylacetylene: from synthesis and electrochemistry to theoretical studies

Abstract

The thiol-yne coupling chemistry between diferrocenylacetylene (FcCΞCFc) 1, bearing two electron rich and redox active ferrocenyl units (Fc = Fe(η5-C5H4)(η5-C5H5)) and an internal triple bond, has been investigated for the...

Electroactive sulfur-rich materials obtained via inverse vulcanization of a diallylsilyl-functionalized ferrocene

“…48,[51][52][53][54] Other relevant and advanced applications of ferrocene-based derivatives have been extensively reviewed. 49,55,56 Recently, we have reported the uses of 1,3-divinyl-1,3dimethyl-1,3-diferrocenyldisiloxane ([(CH 2 vCH)FcMeSi] 2 O), 57 diferrocenylacetylene (FcCuCFc), 58 vinylferrocene (FcCHvCH 2 ), 59 and ethynylferrocene (FcCuCH) 60 (Fc = Fe(η 5 -C 5 H 4 )(η 5 -C 5 H 5 )) as efficient electroactive ferrocene-based precursors for thiol-ene and thiol-yne radical reactions. Such hydrothiolation reactions allowed the incorporation of the electroactive ferrocene as backbone, pendant, or peripheral moieties into polymers and macromolecules with and without silane connecting groups.…”
