In a new synthetic approach for building systems bearing a 1,2,3-triazole moiety, we report here the first Stille cross-coupling reaction of 1,4-disubstituted 5-iodo-1,2,3-triazoles with a range of stannyl derivatives to give the corresponding 5-vinyl-1,2,3-triazoles.
Key words
1,2,3-triazoles - click chemistry - palladium catalyst - Stille cross-coupling reaction - vinyltin reagents
