  摘要：

  Nickel bisdithiolene complexes C-x[Ni(dphdt)(2)] (x = 1 or 0.1, C = tetrabutylammonium (n-Bu4N+); x = 1, C = tetraphenylphosphonium (Ph4P+); dphdt=5,6-diphenyl-1,4-dithiin-2,3-dithiolate) have been synthesized and characterized. The molecular structure of (ph(4)P) [Ni(dphdt)(2)] (CH2CI2) was determined by X-ray analysis. Ni(S2C2S2)(2) core is planar and stacking along the c-axis and the shortest intra-stack S ... S distance is 4.529 Angstrom. According to the cyclic voltammetry of (n-Bu4N) [Ni(dphdt)(2)], two phenyl groups on the dphdt ligand decrease the electron density on the Ni(S2C2S2)(2) core and increase the oxidation potentials compared to those of the (n-Bu4N) [Ni(dddt)(2)] complex (dddt = 5,6-dihydro-1,4-dithiin-2,3-dithiolate). Near-IR spectra of the complexes show that phenyl substitution on the ligand does not give rise to the evident change in transition energy due to the lack of coplanarity with the Ni(S2C2S2)(2) core.

  Heterobimetallic complexes of the type (dppf)PtL (dppf = 1,1'-bis(diphenylphosphino)ferrocene; L = dmit (1,3-dithiole-2-thione-4,5-dithiolate), dddt (5,6-dihydro-1,4-dithiin-2,3-dithiolate), phdt (6-hydro-5-phenyl-1,4-dithiin-2,3-dithiolate), dphdt (5,6-diphenyl-1,4-dithiin-2,3-dithiolate), mtdt (1,2-bis(methylthio)ethylene-1,2-dithiolate), i-mnt (2,2-dicyano-1,1-ethylenedithiolate)) have been synthesized and studied by a high-resolution FAB-MS, cyclic voltammetry and P-31 NMR. (Dppf)Pt(i-mnt) exhibits one reversible redox peak at E-1/2 = 1.225 V and a strong Pt-P coupling constant (J(Pt-P) = 3237 Hz) due to the electron-accepting property of i-mnt ligand. On the contrary, (dppf)Pt(mtdt) shows three reversible redox peaks corresponding to [dppf](0/+) (E-1/2(1) = 0.470 V), [Pt(mtdt)(0/+) (E-1/2(2) = 1.050 V) and [Pt(mtdt)(+/2+) (E-1/2(3) = 1.405 V) processes and a weak Pt-P coupling constant (J(Pt-P) = 2962 Hz) due to relatively strong electron-donor property of mtdt ligand. X-ray structural analyses were performed for the three complexes: (dppf)PtL where L = dmit, phdt and i-mnt. The P2PtS2 core shows a distorted square planar geometry for the three complexes with P(1)-Pt-P(2) bite angle being larger than 96 degrees. The S(1)-Pt-S(2) bite angle of the i-mnt complex is the smallest (74.42 degrees) because of the formation of the four-membered ring. (C) 2001 Elsevier Science Ltd. All rights reserved.

  The facile synthesis of 4 and (±)-6 was carried out via a Diels-Alder type [2+4] cycloaddition reaction of oligomeric dien 8 with styrene or t-stilbene, respectively, as a dienophile by a thermal reaction and/or photoreaction. (±)-6 crystallized as a racemic compound composed of (2R,3R) and (2S,3S) enantiomers.
