The preparation and characterization of the three ferrocene based dithiolane complexes [(eta(5)-C5H5)Fe(eta(5)-C5H4)NHC(O)(CH2)(4)(CHS2CH2CH2) over bar ]1, [(eta(5)-C5H5)Fe(eta(5)-C5H4)CH2OC(O)(CH2)(4) (CHS2CH2CH2) over bar] 2 and [(eta(5)-C5H5)Fe(eta(5)-C5H4)NHC(O)(CH2)(CHS2CH2CH2) over bar] 3, with different spacer groups between the ferrocenyl moiety and the dithiolane unit, are reported. The complexation of 1 and 2, using the oxidative addition of the S-S bonds to Pt(O), is also described, leading to the square planar Pt(II) complexes [Pt(PPh3)(2)(S2CH2CH2CH-kappa(2)-S,S)(CH2)(4)C(O)NH(eta(5)-C5H4)Fe(eta(5)-C5H5)] 4 and [Pt(PPh3)(2) (S2CH2CH2CH-kappa(2)-S,S)(CH2)(4)C(O)OCH2(eta(5)-C5H4)Fe(eta(5)-C5H5)] 5, respectively. The reduction of the S-S bond in 1 and 2 yields the corresponding dithiols; these can be deprotonated and treated with ClSiMe3 to prepare [(eta(5)-C5H5)Fe(eta(5)-C5H4)NHC(O)(CH2)(4)CH(SSiMe3)CH2CH2(SSiMe3)] 7 and [(eta(5)-C5H5) Fe(eta(5)-C5H4)CH2OC(O)(CH2)(4)CH(SSiMe3)CH2CH2(SSiMe3)] 9, respectively. The complexes were characterized via NMR and UV-Vis absorption spectroscopy, cyclic voltammetry and single crystal X-ray diffraction for 1 and 4. (C) 2011 Elsevier B.V. All rights reserved.
