Additionen von Trimethylsilylphosphiten an Pentafluoraceton

1,1,1,3,3-Pentafluoropropane-2-one (3) (pentafluoroacetone) is readily obtained from 1,1,1,3,3,3-hexafluoropropane-2-ol by dehydrofluorination using lithium bis(trimethylsilyl)amide, followed by isomerization of 1,1,3,3,3-pentafluoropropene-2-ol.Pentafluoroacetone adds trimethylsilylphosphites to yield α-trimethylsiloxyphosphonates which, upon thermolysis, furnish (Z)-1,3,3,3-tetrafluoropropenyldialkylphosphites and (Z)-1,3,3,3-tetrafluoro-2-trimethylsiloxypropene.

Method for preparing hydrofluoroether through two-step process

The invention discloses a method for preparing hydrofluoroether through a two-step process. With the method provided by the invention, p-toluensulfonyl chloride and fluorine-containing alcohol are subjected to a reaction to obtain p-toluenesulfonate, and the p-toluenesulfonate and sodium alkoxide are subjected to a Williamson ether synthetic reaction to obtain the hydrofluoroether. The method disclosed by the invention has the advantages of cheap and low-toxicity raw materials, mild and controllable reaction conditions, and high yield.

Fluorinated organic azides-their preparation and synthetic applications

Alkyl azides are widely used in many reactions. Although synthesis of such species is relatively well documented, fluorinated azides, especially with large perfluorinated or highly fluorinated groups, are sometimes tricky to make. The presence of fluorine in reacting molecules, sometimes causes significant changes in the reactivity of reacting species. In this paper we give a short overview of re-examination of currently available methods of synthesis of selected azides with highly fluorinated groups.
