Abstract
A novel protocol for synthesis of (E)-β-Iodovinyl sulfones via NaI-mediated of aryl sulfonyl chloride with alkynes is described, featuring transition-metal-free condition, commercial available substrates, convenient operation, as well as good functional group compatibility. A wide variety of substrate application and good functional group tolerance is provided by this approach, giving multiple (E)-β-Iodovinyl sulfones analogues with excellent yields (up to 98%, >4 g scale).
