  Platinum-Catalyzed Reaction of Alkynes with ArI (Ar = aryl and thienyl) and Ar‘SM (M = Na, K, and Sn(Bu-n)₃):  Three- vs Two-Component Cross-Coupling Reaction

  摘要：

  The Pt-catalyzed reactions of terminal alkynes HCCR (2) with ArI (6) (Ar = aryl and thienyl) and Ar'SM (M = Li, Na, K, and Sn(n-Bu-3)) (7) have been examined. Among them, the combined use of 2- and 3-iodothiophene with PhSK resulted in the formation of (Z)-Ar(H)C=C(SAr')(R) (5) in moderate to good yields. When aryl iodide was employed as a coupling partner, thioether ArSAr' (4), a direct cross-coupling product between 6 and 7, was competitively produced together with 5. The ratios of formation of 514 were significantly dependent on the substituent in Ar of 6 and Ar' of 7 as well as species of 2. The mechanistic study indicated that 4 was produced by the alkyne-participated reaction of 6 with Pt(Ar)(SAr')(PPh3)(2) (1).

• Preparation and some properties of Pt(II) ruthenocenylacetylide complexes

  Ruthenocenylacetylene reacted with trans-PtI(C(6)H(4)X-p)(PPh(3))(2) (X = H, Me, OMe, Cl or CO(2)Me) in the presence of CuI in diethylamine-CH2Cl2 to give the Pt(II) ruthenocenylacetylide complexes, trans-Pt(C=CRc) (C(6)H(4)X-p)(PPh(3))(2) with a good yield. Similarly, cis-Pt(C=CRc)(C(6)H(4)OMe-p)(dppe) was prepared. The structure of trans-Pt(C=CRc)(C(6)H(4)CO(2)Et-p)(PPh(3))(2) was determined by single-crystal X-ray diffraction. No reaction of the trans isomers with DDQ or AgBF4 took place, while the cis isomer was oxidized with AgBF4 to give the coupling products RcC=CC(6)H(5)OMe-p with a low yield. The oxidation of the cis isomer with iodine occurred on the Pt atom to afford p-MeOC(6)H(4)I and PtI2(dppe) as the main products.
• Palladium-catalysed formation of aroylcobalt complexes from iodoarene and tetracarbonylcobaltate anion. Syntheses, characterization and reactivities of model intermediate complexes

  The complex [Pd(PPh(3))(4)] showed good catalytic activity for the formation of aroylcobalt complexes [Co(OCR)(CO)(3)(PPh(3))] from RI (R = aryl), K[Co(CO)(4)] and PPh(3). Attempts to isolate an intermediate Pd-Co complex in this catalytic reaction were unsuccessful, however a series of heterodinuclear complexes [(Ph(3)P)(OC)RPtCo(CO)(3)(PPh(3))] (R = Ph 1a, C(6)H(4)Me-4 1b or Me 1c), [(Me(3)P)(2)(PhCO)PdCo(CO)(4)] 2 and [(Me(3)P)(2)PhPtCo(CO)(4)] 3 have been prepared from reactions of [MR(O3SCF3)(PR'(3))(2)] (M = Pt or Pd, R' = Me or Ph) with K[Co(CO)(4)] as model intermediate complexes. Prior to the formation of complex 1, transient formation of [(Ph(3)P)(2)RPtCo(CO)(4)] was confirmed by P-31 NMR spectroscopy Of the reaction solution. The reaction of [PtPh(O3SCF3)(PMe(3))(2)] with K[Co(CO)(4)] led to the isolation of the corresponding Pt-Co complex 3, while the palladium analogue resulted in the formation of the CO insertion product 2. Crystal structures of compounds 1a, 1c, 2 and 3 were determined by X-ray diffraction analyses. Addition of ligands L such as CO, Bu(t)NC and PMe(3) to 3 in tetrahydrofuran induced heterolytic cleavage of the Pt-Co bond to form [PtPh(PMe(3))(2)L][Co(CO)(4)]. Thermolysis of complexes 1b and 1c under CO at 50 degrees C resulted in reductive elimination of Co(OCC(6)H(4)Me-4)(CO)(3)(PPh(3)) and Co(OCMe)(CO)(3)(PPh(3)), respectively, from the platinum centre. This strongly suggests the involvement of this type of heterodinuclear Pd-Co complex in the catalytic formation of aroylcobalt complexes.

  The character of the electronic transitions in the ultraviolet-visible near infrared (UV-vis-NIR) spectra of platinum-bis(alkynyl) bridged, bis-triarylamine mixed-valence systems trans-[Pt(C CC6H4NAr2)(2) (PR3)(2)](n+) (R = ethyl, Ar = C6H4CH3-4 (1) or C6H4OCH3-4 (2); R = Ph, Ar = C6H4CH3-4 (3) or C6H4OCH3-4 (4), n = 0, 1, 2) has been determined from a combination of spectroscopic measurement and density functional theory calculations. The hybrid functional BLYP35 in combination with a suitable solvent model (i.e., conductor-like screening model (COSMO)) has been used to model the UV-vis-NIR and IR spectroscopic properties of [1-4](+), to confirm the description of [1-4](+) as examples of metal-bridged organic mixed-valence compounds, and to assign the principal features of the electronic spectra, including the triarylamine-based intervalence charge transfer transition located in the NIR region. The successful modeling of the charge distribution within the system demonstrates the utility of the BLYP35-COSMO protocol as a tool for use in the study of intramolecular charge transfer properties in mixed-valence complexes.
