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.

Electron Donor-Acceptor Complex Enabled Decarboxylative Sulfonylation of Cinnamic Acids under Visible-Light Irradiation

Visible-light-induced decarboxylative sulfonylation of cinnamic acids with aryl sulfonate phenol esters enabled by the electron donor-acceptor complex is developed. The method offers a mild and green approach for the synthesis of vinyl sulfones with excellent functional group compatibility under photocatalyst and oxidant-free conditions.

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.

Rapid transformation of sulfinate salts into sulfonates promoted by a hypervalent iodine(III) reagent

An alternative method for forming sulfonates through hypervalent iodine(III) reagent-mediated oxidation of sodium sulfinates has been developed. This transformation involves trapping reactive sulfonium species using alcohols. With additional optimization of the reaction conditions, the method appears extendable to other nucleophiles such as electron-rich aromatic systems or cyclic ethers through a ring opening pathway.

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.

Profiling sulfonate ester stability: Identification of complementary protecting groups for sulfonates

(Figure presented) Sulfonation is prized for its ability to impart water-solubility to hydrophobic molecules such as dyes. This modification is usually performed as a final step, since sulfonated molecules are poorly soluble in most organic solvents, which complicates their synthesis and purification. This work compares the intrinsic lability of different sulfonate esters, identifying new sulfonate protecting groups and mild, selective cleavage conditions.
