tuning by fluorination is very effective for a number of purposes, and currently increasingly investigated for aliphatic compounds. An important application is lipophilicity (log P) modulation. However, the determination of log P is cumbersome for non‐UV‐active compounds. A new variation of the shake‐flask log P determination method is presented, enabling the measurement of log P for fluorinated compounds
通过氟化进行性质调节对于许多目的是非常有效的,并且目前越来越多地研究脂族化合物。一个重要的应用是亲脂性(log P)调节。但是,对于非紫外线活性化合物,log P的测定 很麻烦。提出了摇瓶log P测定方法的新变种 ,可以测量具有或不具有UV活性的氟化化合物的log P,无论它们是亲水的还是亲脂的。无需校准曲线或化合物质量/等分体积的测量。用这种方法,确定了氟化对氟化脂族醇的亲脂性的影响,log P测量氟化碳水化合物的值。报告了有趣的趋势和变化,例如,对相对立体化学的依赖性。
