Perfluorobutane sulfonyl fluoride

As another alternative to triflates, aryl nonaflates (ONf) are easily prepared from phenol and commerically available perfluorobutane sulfonyl fluoride 243, and used for Pd-catalysed coupling with halides [111]. Aryl nonaflates are more reactive than aryl triflates. / -Iodophcnyl nonaflate (244) gives 245 by chemoselective reaction of the... [Pg.60]

Keto-aldehydes (164) were selectively converted to non-conjugated alkynyl ketones (165) possessing an unsubstituted alkyne terminus using the one-pot nonaflation with perfluorobutane-l-sulfonyl fluoride (166) as a base catalysing elimination reaction sequences (Scheme 45). ... [Pg.108]
