The palladium-catalysed vinylic substitution of vinyl triflates with diethylvinyl phosphonate affords the corresponding conjugate dienyl phosphonates. Title compounds are isolated in good to high yields in the presence of K2CO3 and n-Bu4NCl. Best results, however, are obtained by using the K2CO3/KOAc combination.
