Xenon fluoride triflate

The role of the silver salt is not completely understood. No evidence for a single electron transfer mechanism has been found. Although extremely reactive electrophilic fluorinating agents, such as xenon fluoride triflate (FXeOTf) or trifluoromcthanesulfonyloxy fluoride (TfOF), may be generated from the combination of xenon difluoride and silver(l) triflate, the reaction appears to proceed following initial interaction of the alkcnc with the silver ion. ... [Pg.296]

Activation of xenon difluoridc by a silver salt, silver(I) hexafluorophosphonate or silver(I) triflate, is necessary. Higher yields of vinyl fluorides are obtained when silver(I) triflate is used. Reaction times are also considerably shorter (5 to 10 min) in the presence of silver(l) triflate compared to silver(l) hexafluorophosphonate. Since [ FJXeFj has been described,this method is suitable for F-labeling. [Pg.296]
