  A large increase in lipophilicity is observed for CH2/CF2 replacement in the center of di-functional compounds. The increase, in the range of 0.6–1.4 units is for most cases, far above expected values. The effect is nearly additive, thus one can switch from a hydrophilic compound to a lipophilic one using a limited number of H/F exchanges. In this paper, the effect and its origins are explored.

  在双官能化合物的中心观察到 CH 2 /CF 2取代的亲脂性大幅增加。在大多数情况下，增加 0.6–1.4 个单位，远高于预期值。这种效果几乎是叠加的，因此可以使用有限次数的 H/F 交换从亲水性化合物转换为亲脂性化合物。在本文中，探讨了影响及其起源。

  Cyclic voltammetric behaviour of alpha-(phenylthio)acetamides and alpha-(phenylthio)acetates were compared in CH3CN/tetrabutylammonium perchlorate (TBAP) and CH3CN/Et3N . 3HF to assess the influence of fluoride ion on the oxidative pathway. These studies support the Pummerer mechanistic pathway involving an initial attack at sulfur in selective electrofluorination (SEF). A linear correlation between the peak current values in cyclic voltammetry and overall synthetic yield in preparative electrolysis was obtained suggesting the importance of weak blocking or a reactive adsorption effect on the overall synthetic processes. Other factors influencing the adsorption and insulation of electrode surfaces during the SEF are also discussed. (C) 1999 Elsevier Science S.A. All rights reserved.
