  Comparison of Templating Abilities of Urea and Thioruea During Photodimerization of Bipyridylethyelene and Stilbazole Crystals

  摘要：

  AbstractPhotodimerization of cocrystals of four bispyridylethylenes and two stilbazoles with urea as a template in the solid state has been investigated following our success with thiourea. Four investigated olefins photodimerized quantitatively to a single dimer in the crystalline state only. The reactivity of urea–olefin crystals is understood on the basis of their packing arrangements in the crystalline state. In reactive crystals the adjacent reactive molecules are within 4.2 Å and parallel, whereas the unreactive ones have their adjacent molecules are farther than 4.6Å and nonparallel. Thus, with the knowledge of crystal packing the reactivity of urea–olefin crystals is predictable on the basis of Schmidt's topochemical postulates. The templating property of urea, similar to thiourea, derives from its ability to form hydrogen bonds with itself and the guest olefins. Despite the similarities in molecular structures of urea and thiourea their subtle electronic properties, yet to be fully understood, affect the crystal packing and consequently their reactivity in the crystalline state. Further work is needed to fully exploit the templating properties of urea.

  摘要：

  在这项研究中，我们报道了一种非常简单的技术，可以有效地对某些乙烯基吡啶进行光二聚化。通过用几种苯乙烯基唑与分散在非极性（例如环己烷）或中等极性（苯，二氯甲烷，二恶烷）溶剂中的固体草酸二水合物的搅拌混合物进行辐照，可以高收率获得相应的二聚环丁烷加合物，具有极好的区域选择性。和立体选择性。该策略也可以成功地应用于油性，蜡质或什至不溶性斯蒂巴唑。此外，草酸负载量可降低至亚化学计量量。当需要进一步优化时，我们的策略非常灵活，可以确定其他低聚羧酸作为替代添加剂，从而改善甚至推翻区域选择性。
