A convenient method for the preparation of 1,1-dihydropolyfluoroalkanesulfinyl chlorides has been developed basing on the oxidative chlorination of 1,1- dihydropolyfluoroalkyl thioacetates. The dehydrochlorination of the sulfinyl chlorides leads to the formation of new polyfluoroalkylsulfines (fluorinated thioaldehyde-S-oxides). The thermal decomposition of the sulfines results in formation of the

The present invention to a group of compounds of formula (I) useful for the transfer of polyfluoroalkylthiol groups of at least two carbons atoms into a great variety of organic compounds as well as to the process for their preparation. The invention is also directed to the method for the polyfluoroalkylthiolation of an organic compound with the reagents of the invention.
Palladium(0)-catalyzed Sonogashira cross-coupling reaction of 2-fluoroalkylated (Z)-2-fluoro-1-iodoethene, which is easily prepared from commercially available polyfluorinated alcohols in facile three steps, with terminal alkynes in DMF at room temperature for 24 h took place stereospeciflcally to give the corresponding 1-fluoroalkylated (Z)-1-fluorobut-1-en-3-yne derivatives in good to excellent yield. Thus obtained fluoroalkylated 1-fluoroenynes were effectively subjected to addition elimination reaction with various alkynyllithiums at room temperature, leading to 3-fluoroalkylated hex-3-ene-1,5-diyne derivatives in good to high yields with an excellent E selectivity.
