  Novel arylated chloro- and methoxy-1,3-dibutadienes: Influence of substituents on molecular conformation and crystal packing

  摘要：

  Three novel arylated chloro- and methoxy-1,3-butadienes were prepared and studied by a combination of spectroscopic (UV/vis, IR and NMR) and X-ray crystallographic methods. Influence of substituent on the molecular conformation and crystal packing (i.e. intermolecular interactions) was studied. It was predicted that the differences in electronic and steric effects of two chlorine atoms in comparison to two methoxy groups as substituents at different locations in the molecule would provide various packing of the molecules and cause different assumptions for the photochemical behaviour.

  Abstract The photochemical behaviour of mono- and dichloro-substituted butadiene derivatives was studied at low concentrations. These compounds display diverse photochemical behaviour. The α -chloro derivatives photocyclize to give six-membered ring photoproducts. p -Chloro-substituted butadienes undergo intramolecular [2 + 2] cycloaddition followed by formation of benzobicyclic structures.

  Thermal electrocyclization reactions of benzooctatetraenes and benzodecapentaenes substituted with R=H, Cl, and methyl were studied experimentally and computationally. Methyl and unsubstituted benzooctatetraenes and benzodecapentaenes give the [4.2.0]bicyclooctadiene products by 8 pi,6 pi-electrocyclization. Chlorine substitution led to thermal rearrangement of the initially formed 8 pi,6 pi-electrocyclization intermediates to give unprecedented products. (C) 2013 Elsevier Ltd. All rights reserved.
