resulted in the formation of a fluorostilbene derivative, a fluoro enolsilylether and small amounts of 4-(fluoroacetyl)biphenyl, while a similar reaction of 2-methoxymethoxy analog mainly led to the fluorostilbene derivatives and a simple desulfinylation product. In contrast, both sulfoxides reacted with PhLi to give chlorofluoro compounds and fluoro enolethers. In these reactions, the stability

The palladium catalyzedcross-couplingreaction of 1-fluorovinyl halides with organoboranes and organostannanes provide two new facile methods to 1-substituted 1-fluoroolefins. The reactions proceed with retention of configuration in good to excellent yields.
