Synthesis of 1-trimethylsilyl 1,3-dienes by the palladium-catalyzed reaction of trimethylvinylsilane with vinyl iodides/silver nitrate or vinyl triflates
β—Mono- and β,β—disubstituted α,β-unsaturatedesters can be prepared in good yields stereoselectively by the stepwise alkylation and alkoxycarbonylation of 2-bromo-1-alkenylboronates.
