Synthesis of Unsaturated Chloromethyl Ethers

Alkenyl or alkynyl chloromethyl ethers have been prepared from O,S-acetals by reaction with sulfuryl chloride in the presence of cyclohexene or a styrene as a trapping reagent for the sulfenyl halide which is formed in the reaction.Chloromethyl phenyl eth

Syntheses of Sulfinylmethyl Ethers and Conversion of these into Halomethyl and Acyloxymethyl Ethers

Halomethyl ethers can be prepared from sulfinyl ethers by cleavage of the carbon-sulfur bond with thionyl chloride, acetyl chloride or trimethylsilyl halides.In the presence of alkenyl groups in the substrate, acetyl chloride is the reagent of choice.Trifluoroacetic anhydride reacts in the same manner to form the trifluoroacetoxymethyl ether.With acetic anhydride, catalysis by methanesulfonic acid was required.At elevated temperatures in the presence of sodium acetate the products were formed by the Pummerer rearrangement.
