nC8F17), which enables the direct insertion of CF3 and perfluoroalkyl groups into triazole ring systems. The azidoperfluoroalkanes show good reactivity with terminal alkynes in copper(I)‐catalyzed azide–alkynecycloaddition (CuAAC), giving access to rare and stable N‐perfluoroalkyl triazoles. Azidoperfluoroalkanes are thermally stable and the efficiency of their preparation should be attractive for
我们报告了叠氮基三氟甲烷(CF 3 N 3)和更长的全氟化碳链类似物(R F N 3; R F = C 2 F 5,n C 3 F 7,n C 8 F 17)的有效且可扩展的合成,这使CF 3和全氟烷基直接插入三唑环系统。在铜(I)催化的叠氮化物-炔烃环加成反应(CuAAC)中,叠氮全氟烷烃与末端炔烃显示出良好的反应性,从而获得稀有且稳定的N全氟烷基三唑。叠氮全氟烷烃具有热稳定性,其制备效率对于发现计划应具有吸引力。
Supramolecular Aggregation of Perfluoroorganyl Iodane Reagents in the Solid State and in Solution
to the formation of various assemblies with different dimensions in the solidstate. The protonation of the reagents results in the formation of entirely different supramolecular structures, which are supported by hydrogen bonding. The structural features of the reagents in the solidstate reflect well their behavior in solution, and the I–C(RF) bond is influenced by the coordination of Lewis basic
描述了不同的全氟有机基碘的晶体结构,包括四种新的苯并恶唑衍生物,其R F = n- C 3 F 7,n- C 4 F 9,n- C 8 F 17和C 6 F 5。在所有化合物中,碘原子均显示出显着的路易斯酸度,第二个键合相互作用容易填充第四个配位位点,从而产生方平面配位。尽管这种几何形状是苯并恶唑的良好模型,但苯并恶唑啉酮衍生物往往会通过额外的弱I ···进一步聚集。O或I ···芳基接触。不同的相互作用导致在固态下形成具有不同尺寸的各种组件。试剂的质子化导致形成完全不同的超分子结构,并通过氢键得到支持。固态试剂的结构特征很好地反映了它们在溶液中的行为,并且I–C(R F)键受Lewis碱性溶剂与碘原子的配位作用以及与质子溶剂的氢键作用的影响。与具有更长RF链的衍生物相比,这些溶剂效应对于包含三氟甲基片段的试剂而言更为明显。
