title: Highly regio- and stereoselective synthesis of tetrasubstituted olefins by the three-component tandem reaction of allylzinc bromide, acetylenic sulfone, and halohydrocarbon.
abstract: [reation: see text]. Tetrasubstituted olefins containing a 1,4-diene structural unit can be regio- and stereoselectively constructed in one pot by the allylzincation of acetylenic sulfones, followed by Negishi cross-coupling with halohydrocarbons in the presence of catalytic Ni(PPh3)2Cl2.
