An efficient synthesis of 2,3,5,6-tetrafluoro-4-iodo-benzaldehyde (1) is presented. This new compound was readily obtained via iodination at low temperature of the lithio derivative of 2-(2,3,5,6-tetrafluoro-phenyl)-[1,3]dioxolane (4). The crystal structure of 1 consists of linear polymeric chains, with non-covalent O⋯I bonding as the directing interaction, responsible for the observed assembly. Aldehyde
提出了2,3,5,6-四氟-4-碘-苯甲醛(1)的有效合成。通过在低温下碘化2-(2,3,5,6-四氟-苯基)-[1,3]二氧戊环(4)的硫代衍生物,容易获得该新化合物。的晶体结构1由线性聚合物链,以非共价ö⋯我接合作为导向相互作用,负责观察到的组件。醛1还用于合成5,10,15,20-四(五氟苯基)卟啉(6),这是超分子组装体的潜在前体。
