We synthesized a series of polyfluoro-amino-stilbenes in satisfactory yields by Wittig reaction of 4-piperazinyl-benzalhehydes with pentafluoro-benzylidene-triphenyl-phosphorane and we analyzed the photochemical behavior of these stilbenes in the solid state; thanks to arene–perfluoroarene π–π interactions, some of them have shown a good propensity to give the corresponding cyclobutane photodimers
我们通过4-哌嗪基-苯并甲醛与 五氟亚苄基三苯基膦并且我们分析了这些斯蒂尔苯在固态下的光化学行为;多亏了芳烃–全氟芳烃 π–π相互作用,其中一些已经显示出给出相应的良好趋势 环丁烷光二聚体的定量收率。溶液和聚合物基体中的光环化都是可逆的,从而提供具有不同顺式-反式立体选择性的相应的对苯二酚。
