Novel preparative methods for fluoroalkyl arylsulfinyl compounds are disclosed. Fluorinated compounds as useful fluorinated compounds, intermediates, or builing blocks are disclosed. Useful applications of the fluoroalkyl arylsulfinyl compounds are shown.
cycloalkanes with alkylarylsulfinates has been performed. Using iodine as the catalyst, through C −H bond activation and sulfinates reduction, a wide range of thioethers were produced in moderate to high yields. Additionally, various thiocarboxylic esters can also be produced by simply performing the reaction under CO pressure. Notably, this is the first report in which alkylarylsulfinates were used as

The direct transformation of various thiols and simple alcohols with N-bromosuccinimide into sulfinic esters has been investigated by using different categories of base/acidic catalysts as well as co-solvents under varied reaction conditions. The reaction was found out to afford the sulfinic esters with high yields in the absence of catalysts, especially within the shorter time under the acceleration

10-phenanthroline-catalyzed direct sulfenylation reactions was reported. In this reaction, heteroarenes such as indoles, and pyrroles serve as nucleophiles by installing a arylthio group at the C3 and C2 position of heterocycles, respectively. With readily accessible and free of unpleasant odor ethyl arylsulfinates as sulfur reagents, the metal-free-catalyzed direct sulfenylation of N-heteroarenes has been
据报道,通过NH 4 I / 1,10-菲咯啉催化的直接亚磺酰基化反应可有效合成N-杂环芳基硫化物。在该反应中,通过在杂环的C 3和C 2位置分别安装芳硫基,使杂芳烃如吲哚和吡咯成为亲核试剂。随着容易获得并且没有令人不愉快的气味的芳基亚磺酸乙酯作为硫试剂,已经开发了无金属催化的N-杂芳烃的直接亚磺酰基化。即使在克规模上,也以中等至优异的产率获得了3-芳硫基吲哚和2-芳硫基吡咯的衍生物。该反应对于广泛的底物是通用的,并且显示出对多种官能团的良好耐受性。
Copper-Catalyzed Oxidative Reaction of β-Keto Sulfones with Alcohols via C−S Bond Cleavage: Reaction Development and Mechanism Study
A Cu‐catalyzed cascade oxidative radical process of β‐keto sulfones with alcohols has been achieved by using oxygen as an oxidant. In this reaction, β‐keto sulfones were converted into sulfinate esters under the oxidative conditions via cleavage of C−S bond. Experimental and computational studies demonstrate that a new pathway is involved in this reaction, which proceeds through the formation of the
