Resumen

Oxidative addition reaction of dipyridyl ditellurides to [Pt 2(dppm) 3] gave two types of complexes, [Pt{2-Te-C 5H 3(3-R)N} 2(dppm)] (1) and [Pt{PPh 2C(TeC 5H 3(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 [PtCl 2(dppm)] and NaTeC 5H 3(3-R)N. Treatment of [Pt(dppe) 2] with dipyridyl ditellurides yielded an oxidative addition product, [Pt{2-Te-C 5H 3(3-R)N} 2 (dppe)] (3) (R = H or Me), exclusively. In a substitution reaction of [PtCl 2(dppe)] with NaTeC 5H 3(3-Me)N a complex of composition Pt{TeC 5H 3(3-Me)N}(dppe)Cl (4) wasformed. The reaction between either [Pt(dppp) 2] and Te 2(C 5H 3(3-Me)N) 2or [PtCl 2(dppp)] and NaTeC 5H 3(3-R)N afforded a mixture of [Pt{2-Te-C 5H 3(3-Me)N} 2(dppp)] (5) and [Pt 3Te 2(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{PPh 2C(TeC 5H 4N) 2PPh 2} 2] and [Pt 2{TeC 5H 3(3-Me)N} 2(dppe) 2][BPh 4] 2 were established by single-crystal X-ray diffraction analyses. The bonding, charge transfer, and geometry of compounds [Pt{2-Te-C 5H 3(3-R)N} 2(dppm)] (1), [Pt{PPh 2C(TeC 5H 3(3-R)N) 2PPh 2} 2] (2), and [Pt 3Te 2(dppp) 3] 2+ (6) have been analyzed through relativistic density functional calculations.
