Stereoselective Synthesis of 1,4-Dienes through Sequential Cross Coupling of (E)-α-Selanylvinylstannanes†
Abstract
(E)-α-Selanylvinylstannanes underwent palladium-catalysed coupling reaction with allyl bromides to give 1,4-dienyl selenides; the products can react with Grignard reagent to afford 1,4-dienes in the presence of Ni(dppp)2Cl2.
