  Thermo-cage opening of 4-iodo-1-vinylcubane to a novel styrene derivative

  摘要：

  Cubane (1) and its derivatives have been cited for exhibiting unusual properties, including explosive and antiviral activity. An additional characteristic of these compounds is their tendency to undergo cage opening under certain conditions. In our attempt to polymerize 4-iodo-1-vinylcu bane (4), 4-vinyl-trans-beta-iodostyrene (10) was formed quantitatively. By examining both the thermolytic and Lewis acid-assisted rates, a possible mechanism for the rearrangement of 4 -> 10 has been proposed. (c) 2008 Elsevier Ltd. All rights reserved.

  A liquid crystal compound is to be obtained that has stability to heat, light and so forth, a high clearing point, a suitable optical anisotropy, a large negative dielectric anisotropy, and excellent compatibility with other liquid crystal compounds. A liquid crystal composition containing the compound is also to be obtained that has a low viscosity, a suitable optical anisotropy, a suitable negative dielectric anisotropy, a low threshold voltage, a high maximum temperature of a nematic phase (phase transition temperature from a nematic phase to an isotropic phase), and a low minimum temperature of a nematic phase. A compound having a hydrocoumarin skeleton is synthesized, and a liquid crystal composition containing the compound is produced.
