|Abstract:||Dimeric thiolato-bridged Ni(II) and Pt(II) NHC complexes 2 and 4 have been synthesized from ligand precursor A through a combined and in situ deprotonation/hydrolysis protocol of a thioester-functionalized benzimidazolium salt in the presence of the respective metal salts. Reactivity studies of 2 and 4, and their previously reported Pd(II) analogue 1a toward either Me 3OBF4, NaOH, or Na2S·9H2O revealed clear differences. Complex 2 decomposed when treated with Me 3OBF4. On the other hand, its reaction with aqueous NaOH solution in the presence of NaBF4 yielded trinuclear [Ni 3S3O] complex 6, which possesses an interesting [Ni 3S3] triangle with a capping μ3-oxido ligand. Pt(II) analogue 4 was converted to the tetranuclear [Pt 4S4] macrocycle 5 when treated with Me3OBF 4, in analogy to the result from 1a, while no defined products could be isolated when 4 was treated with either NaOH or Na2S· 9H2O. Pd(II) analogue 1a reacted with Na2S·9H 2O to give the tripalladium [Pd3S3S] complex 7 bearing a capping μ3-sulfido ligand. © 2013 American Chemical Society.|
