  Polyfluorination Using IF₅

  摘要：

  The polyfluorination of alpha-(arylthio)carbonyl compounds was achieved by a successive application of polyfluorination using IF5, Friedel Crafts arylation, and desulfurizing fluorination using IF5. Three to six fluorine atoms were selectively introduced to the carbons located between the aromatic ring and the carbonyl group.

  difluoroalkylation of difluoroenoxysilanes is developed. The reaction includes a strategy of combination of two fluorine-containing functional groups, which confers the reaction with characteristics like high efficiency, mild conditions, and broad scope. A variety of fluoroalkyl halides including perfluoroalkyl iodides, bromo difluoro esters and amides can be employed as radical precursors. Control experiments

  开发了一种通过光催化二氟烯氧基硅烷的二氟烷基化构建各种全氟酮的温和简便的方法。该反应采用两个含氟官能团结合的策略，具有高效、条件温和、适用范围广等特点。包括全氟烷基碘化物、溴二氟酯和酰胺在内的多种氟代烷基卤化物可用作自由基前体。对照实验表明该反应可能涉及单电子转移途径。
