A metal-free yne-addition/1,4-aryl migration/decarboxylation cascade reaction of alkynoates with Csp3–H centers†
Abstract
A metal-free cascade reaction of aryl alkynoates with five different types of radical precursors (R–H) through an yne-addition/1,4-aryl migration/decarboxylation process was reported, which allowed facile and convenient access to functionalized vinyl products with “R” and protons located at the identical carbon of the formed double bond.
