Preparation of Iodide-Thiolate Bridged Binuclear Ni-Ni Complexes via Versatile Reaction of Labile Ni(II)-S(thiolate) Bond

Abstract:

The reaction between Fe(CO)₄I₂ and Ni(SR)₂(dppe) affords NiI₂(dppe) due to the nucleophilic attack of iodide on the labile Ni-S(thiolate) bonds. The iodide-dithiolate-bridged binuclear Ni-Ni complexes [(dppe)Ni(µ-I)(µ-pdt)Ni(dppe)]I is readily prepared from the reaction between [NiI₂(dppe)] and [Ni(pdt)(dppe)] [dppe = 1,2-bis(diphenyl phosphino)-ethane; pdt = 1,3-propane-dithiolate] in CH₂Cl₂ as a result of attack on Ni-I bond by the lone pairs of electrons on thiolato sulfur donors. The reaction between [FeCp(CO)₂I] and [Ni(pdt)(dppe)] in CH₂Cl₂ processes extremely slowly. However, upon metathesis with NH₄PF₆, the iodide-thiolate bridged binuclear Ni-Ni complexes [(dppe)Ni(µ-I)(µ-pdt)Ni(dppe)]PF₆ is formed from the reaction of iodide and the Ni(II)-S bonds. The reaction between [NiCl₂(dppe)] and NH₄PF₆ and [Ni(pdt)(dppe)] gives a binuclear complex [(dppe)Ni(µ-pdt)Ni(dppe)]PF₆ without a halide-bridge. These results suggest that the reactivity of Ni-SR bonds in the Ni-thiolate-phosphine complexes is tunable with regard to the electronic environment of second metal ion and the different reactivity of iodide moiety. Electrochemical and crystallographic results are also analyzed for relevant compounds.
