Abstract
| - 1-(3‘-Chlorophenyl)-1-trimethylsilyl-1,2,2,2-tetrafluoroethanehas been prepared in an excellent yield by the Mg-promoteddefluorinative silylation of 3-chloropentafluoroethylbenzeneand transformed to a series of 1-substituted 2,2-difluorostyrenes by fluoride ion-catalyzed 1,2-desilylative defluorination.
