  名称：

  F-2,4-二甲基-3-乙基-3-戊基和 F-2,4-二甲基-3-异丙基-3-戊基；通过将氟或三氟甲基加成到全氟烯烃上制备的稳定的叔全氟烷基

  摘要：

  可以预期小 hfc 和弱 CIDNP 效应。在 H1 的 CIDNP 实验部分，光谱清楚地显示了发射，而 HI 被 H4 的强烈增强吸收所掩盖。我们进一步注意到，局部自由基阳离子 5a,b 尽管与观察到的极化不相容，但不能排除它是快速重排的主要氧化产物（7 5 3 的形成需要 C4 和 C2 的再杂交。这结构可能允许两个烯丙基系统在 C 和 CzJ 或 Cz 和 C4 的 a 轨道之间有一些重叠。但是，只有以严重畸变为代价才能实现显着的重叠。自由基阳离子 3 是一个有趣的例子一个新兴的自由基阳离子家族，其结构与它们的母体分子完全不同。事实上，自由基阳离子类似于相应热异构化的过渡态几何形状。这些自由基阳离子的详细讨论正在准备中。s) 双烯丙基，共振稳定 3.

  Articles, methods of making, and uses for modifying surfaces for simultaneously providing repellency and selective binding of desired moieties are disclosed. The repellant surfaces comprise a substrate and a lubricating layer immobilized over the substrate surface having a lubricating liquid having an affinity with the substrate. The substrate and the lubricating liquid are attracted to each other together by non-covalent attractive forces. The repellent surface further includes a binding group extending over the surface of the lubricating layer and the binding group has an affinity with a target moiety. The lubricating layer and the substrate form a slippery or repellent surface configured and arranged for contact with a material that is immiscible with the lubricating liquid and the immiscible material contains the target moiety.
