Concise and general synthesis protocols are reported to generate all- mono-, di- and tri-alkylated cyclohexanes where a single fluorine is located on the remaining carbons of the ring. The alkyl groups are positioned to lie equatorially and to have triaxial C-F bonds imparting polarity to these ring systems. Intermolecular electrostatic interactions in the solid-state structure of the trialkylated systems are explored and the resultant supramolecular order opens up prospects for design in soft materials.
有报道称,通过简洁通用的合成方案可以制得所有单、二和三烷基取代环己烷,其中一个氟原子位于环上剩余的碳原子上。这些烷基基团位于环己烷的赤道位置,具有三轴 C-F 键,使这些环系具有极性。三烷基取代体系在固态结构中的分子间静电相互作用得到了研究,所得超分子有序性为软材料的设计开辟了前景。
