Novel, readily occurring, and stereoselective synthesis of conjugated trienes using 2-trialkylstannyl-2,5-dihydrothiophene S,S-dioxides
Abstract
Conjugated trienes have been synthesised readily and stereoselectively by the coupling reaction of 2-tri-n-butylstannyl-2,5-dihydrothiophene S,S-dioxides with vinyl iodides in the presence of tetrakis(triphenylphosphine)palladium(0), followed by desulphonylation.
