Abstract

Oxidative addition reaction of dipyridyl ditellurides to [Pt ₂(dppm)₃] gave two types of complexes, [Pt{2-Te-C ₅H₃(3-R)N}₂(dppm)] (1) and [Pt{PPh ₂C(TeC₅H₃(3-R)N)₂PPh ₂}₂] (2) (R = H or Me), in ∼65 and ∼20% yield, respectively. Both these complexes are also formed in the substitution reaction between [PtCl₂(dppm)] and NaTeC₅H₃(3-R)N. Treatment of [Pt(dppe)₂] with dipyridyl ditellurides yielded an oxidative addition product, [Pt{2-Te-C₅H₃(3-R)N} ₂ (dppe)] (3) (R = H or Me), exclusively. In a substitution reaction of [PtCl₂(dppe)] with NaTeC₅H₃(3-Me)N a complex of composition Pt{TeC₅H₃(3-Me)N}(dppe)Cl (4) wasformed. The reaction between either [Pt(dppp)₂] and Te₂(C ₅H₃(3-Me)N)₂or [PtCl₂(dppp)] and NaTeC₅H₃(3-R)N afforded a mixture of [Pt{2-Te-C ₅H₃(3-Me)N}₂(dppp)] (5) and [Pt ₃Te₂(dppp)₃]²⁺ (6), which were separated by column chromatography. All the complexes were characterized by elemental analyses and NMR (¹H, ³¹P, ¹⁹⁵Pt) spectroscopy. The molecular structures of [Pt{PPh₂C(TeC ₅H₄N)₂PPh₂}₂] and [Pt₂{TeC₅H₃(3-Me)N}₂(dppe) ₂][BPh₄]₂ were established by single-crystal X-ray diffraction analyses. The bonding, charge transfer, and geometry of compounds [Pt{2-Te-C₅H₃(3-R)N}₂(dppm)] (1), [Pt{PPh₂C(TeC₅H₃(3-R)N)₂PPh ₂}₂] (2), and [Pt₃Te₂(dppp) ₃]²⁺ (6) have been analyzed through relativistic density functional calculations.
