Abstract

Treatment of the complexes trans-[M(PBu3)2Cl 2] (M = Ni, Pd or Pt) with one equivalent of the reagent Me 3SnC≡C-R-C≡CSnMe3 (R = p-C6H 4) affords the polymeric species trans-[-M(PBu3) 2-C≡C-R-C≡C-]n, where as if two equivalents of the tin reagent are used in this reaction, when M = Pt, the complex trans-[Me3SnC≡C-R-C≡C-Pt(PBu3) 2-C≡C-R-C≡CSnMe3] may be isolated, a precursor for further syntheses; the complex mer-trans-[Rh(PMe3) 3(SnMe3)(C≡CPh)2] has been prepared by the addition of Me3SnC≡CPh to [Rh(PMe3) 4][Cl], and this latter species, when treated with Me 3SnC≡C-R′-C≡CSnMe3 (R′ = p-C 6H4-C6H4-p), affords the oligomeric compound mer-trans-[-Rh(PMe3)3(SnMe3)- C≡C-R′-C≡C-]n.
