SYNTHESIS OF FLUORINATED VINYL SULFIDES AND SELENIDES

The reaction between fluoroolefins 1 and 10e and benzenesulfenyl or selenenyl halides 6 is found to be solvent-dependent and gives in most cases predominantly the regioisomer 8.The structure of adducts 8 and 9 are ascertained by 1H, 19F and 77Se NMR spectroscopy.Compounds 8 are easily halogenated and treatment of the products with magnesium or zinc leads to the desired polyfluorovinyl sulfides and selenides 10.A second route of synthesis of these reagents results from the reaction of fluorovinyllithio-derivatives 11 with benzenesulfenyl or selenenyl halides.Olefin 10e is also obtained from the selenoacetal 8t of trifluoroacetaldehyde.

Fluoride Ion Elimination-Addition Reactions. Synthesis of 2,2-Difluoroethenyl Phenyl Selenide and 2,2,2-Trifluoroethyl Phenyl Selenide

2-Chloro-2,2-difluoroethyl phenyl selenide (1) reacts with KF and a catalytic amount of 18-crown-6 to give 2,2-difluoroethenyl phenyl selenide (3) and 2,2,2-trifluoroethyl phenyl selenide (4).The latter is formed by an elimination-addition sequence. 2-Bro
