  Weak interactions direct crystal packings of arylated 1,3-butadienes

  摘要：

  Four novel aryl butadienes (substituted with R = Cl, OCH3, NO2 and H) were prepared and characterised by X-ray diffraction, IR, UV/Vis and NMR spectroscopies. A comparative analysis of crystal packings was aimed to determining influence of weak interactions: C-H center dot center dot center dot O and C-H center dot center dot center dot Cl hydrogen bonds, C-H center dot center dot center dot pi interactions and dispersion interactions. Since no proton donors is present and since the molecules are sterically very similar, these weak interactions are responsible for wide variation in 3D packing and supramolecular motives.

• Photochemical Approach to New Polycyclic Substrates Suitable for Further Photocatalytic Functionalization
  作者：Dragana Vuk、Željko Marinić、Irena Škorić

  DOI：10.5562/cca2454

  日期：——

  New polycyclic compounds are synthesized by photocycloaddition reactions of methoxy, methyl or phenyl substituted butadiene derivatives 11-14. Mono- and dimethoxy butadiene derivatives 11 and 12 undergo intramolecular [2+2] photocycloaddition giving benzobicyclo[3.2.1]octadiene structures (endo-15, endo,trans-17) as main products. As minor photoproducts tricyclic compounds endo-16 and endo,trans-18 are isolated, respectively, formed by [4+2] photoinduced cycloaddition of the starting molecules. The reaction of compounds 13 and 14 is more selective and only benzobicyclo[3.2.1]octadienes endo,endo-19 and endo,endo-20 are formed, respectively. New bicyclo[3.2.1]octadienes with isolated double bond can be suitable substrates for further efficient photocatalytic oxygenations in course of new functionalized polycycles, potentially new biologically active compounds.
