Novel routes to fluorinated ethers containing a fluorosulfonyl group

The chloroxy compounds ClOCF2CFXSO2F (X=F, CF3) have been reacted with several simple olefins to give ethers.In the case of unsymmetrical olefins the reaction mainly follows an electrophilic cis addition with the positive polarized chlorine adding in a Markovnikov manner.One example of the conversion of a sulfonyl fluoride to its corresponding acid is given.The latter gives the respective sulfonyl chloride with phosphorus pentachloride.
