    The formation of ordered polydiacetylenes (PDAs) from conjugated triynes and longer polyynes has proven challenging due to the low stability of the starting materials and the possibility of varying regiochemistry for the polymerization. We report here the preparation of host-guest cocrystals of diiodohexatriyne and diiodooctatetrayne, each with a bis(nitrile)oxalamide host. Single-crystal X-ray diffraction studies show that the halogen-bonding interactions between the host and guest align the diiodopolyyne monomers with the proper parameters for 1,4-topochemical polymerization. Using Raman spectroscopy, solid-state C-13 MAS NMR, and single-crystal X-ray diffraction, we have demonstrated the formation of a single highly ordered PDA, poly(iodoethynyliododiacetylene) (PIEDA), from the 1,4-polymerization of diiodohexatriyne. Diiodooctatetrayne also forms ordered cocrystals, but attempts to form polymer from these crystals led to disordered species. This work represents the first reported single-crystal-to-single-crystal 1,4-polymerization of a conjugated triyne.

  • An Iterative Method for the Synthesis of Symmetric Polyynes
    作者:Racquel C. DeCicco、Allison Black、Lei Li、Nancy S. Goroff
    DOI:10.1002/ejoc.201200442
    日期:2012.9
    An iterative synthetic route for obtaining symmetric polyynes was developed, consisting of a series of iodination and Stille coupling reactions. The starting materials employed in this pathway are simple and can be prepared easily. Polyynes containing up to seven C≡C bonds were synthesized using this method. This route is particularly effective for accessing polyynes with an odd number of C≡C bonds
