  摘要：

  The preparation and structures of three diborane(4) compounds ape described. The compound B-2(3,4-S2C4H2-1-S)(2)[2,2'-bi(1,3,5,2-trithiaborapentalene), C8H4B2S6] is planar and lies at a crystallographic inversion centre. The amine adducts [B-2(C3S5)(2)(NHMe2)(2)] [2,2'-bis(dimethylamino)-2,2'-bi(1,3,4,6,2-tetrathiaborapentalene-5-thione), C10H14B2N2S10] and [B-2(1,2-S2C2H4)(2)(NHMe2)(2)]. 0.33CH(2)Cl(2) [1,2-bis(dimethylamino)-1,1:2,2-bis(dimethylenedithioxy)diborane(4) dichloromethane solvate, C8H22B2N2S4. 0.33CH(2)Cl(2)] contain dimethylamine ligands bound to each boron in an anti conformation about the B-B bond, with tetrahedral geometry at the B atoms. The crystal structures display a number of S ... S interactions, which appear to dictate the packing arrangements.

• [4+3] Cycloaddition of Donor-Acceptor Cyclopropanes with Amphiphilic Benzodithioloimine as Surrogate for <i>ortho</i> -Bisthioquinone

  Donor–acceptor cyclopropanes were reacted with amphiphilic benzodithioloimine to give seven‐membered heterocycles with two sulfur atoms. Formally, this transformation can be regarded as a [4+3] cycloaddition reaction of the three‐membered ring and ortho‐bisthioquinone. The benzodithioloimine serves as a surrogate for this highly reactive diene. The structure of the products was confirmed by X‐ray crystallography

  Selective chlorination of thiophene-2,3-dithiol with SO2Cl2 generates the corresponding sulfenyl chloride, 2,3-C4H2S(SCl)2. Subsequent condensation with Me3SiN3 yields the thiophenodithiazolylium salt [C4H2S3N]Cl, [TDTA]Cl. The structure of the cation, TDTA+, was established by X-ray diffraction as both its AsF6− and HSO4− salts. Reduction of [TDTA]Cl with Ag powder yields the radical TDTA˙ which was characterised by X- and Q-band (9 and 34 GHz) EPR and ENDOR studies. The spin density distributions estimated from the EPR/ENDOR measurements were found to be in very good agreement with those determined by DFT (B3LYP/6-31G*) indicating that ca 10% of the spin density is delocalised onto the thiophene ring. Comparison of the spin density distributions in TDTA˙ and the isoelectronic trithiatriazapentalenyl radical C2S3N3, TTTA˙, indicates that replacement of N by C–H leads to a localisation of the spin density on the dithiazolyl ring.

  用 SO2Cl2 对噻吩-2,3-二硫醇进行选择性氯化，可生成相应的亚磺酰氯 2,3-C4H2S(SCl)2。随后与 Me3SiN3 缩合，可生成噻吩二噻唑鎓盐 [C4H2S3N]Cl，即 [TDTA]Cl。通过 X 射线衍射，确定了阳离子 TDTA+ 的 AsF6â 盐和 HSO4â 盐的结构。用银粉还原 [TDTA]Cl 会产生自由基 TDTAË，并通过 X 波段和 Q 波段（9 和 34 GHz）的 EPR 和 ENDOR 研究对其进行了表征。根据 EPR/ENDOR 测量结果估算出的自旋密度分布与 DFT（B3LYP/6-31G*）确定的自旋密度分布非常一致，表明约有 10% 的自旋密度被分散到噻吩环上。比较 TDTAË 和等电子三硫杂三氮杂环戊烯基 C2S3N3（TTTAË）中的自旋密度分布表明，用 CâH 替代 N 会导致自旋密度集中在二噻唑环上。

• New π-electron donor systems based on acenaphtho[1,2-b][1,4]dithiine
  作者：Martin R. Bryce、Antony Chesney、Alexander K. Lay、Andrei S. Batsanov、Judith A. K. Howard

  DOI：10.1039/p19960002451

  日期：——

  Syntheses of the acenaphtho[1,2-b] [1,4] dithiine derivatives 12, 25 and 29 are reported. Cyclic voltammetric studies reveal that these compounds undergo reversible single-electron oxidations at < 1.0 V, vs. Ag/AgCl. Lithiation of compound 12 with BuLi (2 equiv.) followed by addition of either methyl iodide or ethyl chloroformate yielded the unstable ring-opened acetylene derivatives 22a and 22b, respectively. A new synthesis of 1,2-diselenine derivative 33 is reported. Compound 25 formed 1:1 charge-transfer complexes with 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) and with 2,5-dibromo-TCNQ, both of which were electrical insulators. The X-ray crystal structures of compound 25, a charge-transfer complex 25:Br,TCNQ (1:1 stoichiometry) and compound 33 are reported. In the structure of 25:Br,TCNQ, molecules of 25 and Br,TCNQ form mixed stacks. The folding of the donor along the S ... S vector in the complex is 17 degrees (ef. 48 degrees in pure 25) and the conformation of 25 is discussed in the light of previous studies on 1,4-dithiine derivatives. An interesting feature of the crystal structure of 33 is the formation of pseudo-dimers with two short intermolecular Se Se contacts.
• Synthesis of Trithienylenevinylenes Bearing Dithiocarbonate Groups and Their Dithiophene−Tetrathiafulvalene Derivatives
  作者：Xin Chen、Norma R. de Tacconi、Ronald L. Elsenbaumer

  日期：2009.12.4

  A series of conjugated trithienylenevinylene compounds bearing dithiocarbonate groups were prepared by Wittig reactions. Dithiophene-tetrithiafulvalene (DT-TTF) derivatives can be readily prepared through trialkylphosphite-mediated coupling reactions of these trithienylenevinylene materials. All compounds were characterized by NMR, FT-IR, UV-vis, and mass spectroscopy.
