Herein, a solution phase NMR conformer population analysis is employed to probe the effect of remote electronic perturbations on the conformationalequilibria of a series of para-substituted β-fluorosulfides (1), sulfoxides (2) and sulfone derivatives (3). Conformations that allow for stabilizing stereoelectronic (σC–H → σ*C–F) and electrostatic (Fδ−…Sδ+) interactions predominate: this is consistent

Most existing methods for the synthesis of alkylaryl thioethers require the use of mercaptans as the starting materials, which comes with practical limitations. Reactions of diaryliodonium salts with xanthate salts, easily prepared from the corresponding alcohols and CS2, under the developed conditions represent an operationally simple, thiol-free method for the synthesis of these valuable compounds
大多数现有的烷基芳基硫醚的合成方法需要使用硫醇作为起始原料,这存在实际限制。二芳基碘鎓盐与黄原盐(很容易由相应的醇和CS 2制备)在开发的条件下的反应代表了一种操作简单、无硫醇的合成这些有价值的化合物的方法。该方案具有高官能团耐受性,可应用于后期 C-H 官能化和 CD 3 S 基团的引入。
