Metal-Free Three-Component Oxyalkynylation of Alkenes.

Yangshan Li1, Ran Lu1, Shutao Sun1, Lei Liu1,2.   

Abstract

An unprecedented (NH4)2S2O8 mediated metal-free three-component alkene oxyalkynylation using H2O or alcohol as oxygenation agent is described. Mechanistic studies suggested that the reversed regioselectivity should be dictated by an alkene radical cation intermediate.
