Modellreaktionen zur Umsetzung von Ferrocen-1,1′-dithiol mit Diolefinen:II. Die Saeuren- und Basenkatalysierten Reaktionen von Ferrocenthiolen mit aktivierten Olefinen
Both ferrocenethiol and ferrocene-1,1′-dithiol, Fe(C5H5)(C5H4SH) and Fe(C5H4SH)2, add to activated olefins to give 1:1 and 1:2 adducts, respectively.The base-catalysed (NEt3) reactions of the monofunctional ferrocenethiol with the mono-olefins methyl methacrylate, methyl vinyl sulfone and benzylidene acetone lead to expected 1:1 adducts whereas 2:1 adducts are obtained with bifunctional olefins such as divinyl sulfone and dibenzylidene acetone.The corresponding bifunctional ferrocene-1,1′-dithiol gives 1:2 adducts with methyl methacrylate, methyl vinyl ketone and benzylidene acetone.For comparison, the aliphatic 2-ferrocenyl-ethanethiol, Fe(C5H5)(C5H4-CH2CH2SH), was reacted with methyl vinyl sulfone and divinyl sulfone.In all cases, the disulfides Fc-SS-Fc and Fc-CH2CH2-SS-CH2CH2-Fc, respectively, are also formed.The acid-catalysed (HCl) reactions of ferrocenethiol and ferrocene-1,1′-dithiol, Fe(C5H5)(C5H4SH) and Fe(C5H4SH)2, with isobutyl vinyl ether produce the expected 1:1 and 1:2 adducts although the formation of dimercaptals is also possible.Thus the reaction of ferrocene-1,1′-dithiol with isobutyl vinyl ether leads to both the 1:2 adduct and the 2-methyl 1,3-dithia-<3>ferrocenophane, Fe(C5H4S)2CH(CH3), and the HCl-catalysed addition of ferrocenethiol to 1,4-butadienol divinyl ether gives 1,1-di(ferrocenylmercapto) ethane, CH3CH(SFc)2.The new sulfur derivatives of ferrocene were characterized by 1H and 13C NMR spectroscopy.Keywords: Iron; Ferrocene; Ferrocene thiol; Addition to olefins; NMR
