Abstract

Herein we report a facile, mild reaction protocol to form carbon‐carbon bonds in the absence of transition metal catalysts. We demonstrate the metal‐free alkenylation reactions of aryl esters with α‐diazoesters to give highly functionalized enyne products. Catalytic amounts of tris(pentafluorophenyl)borane (10–20 mol%) are employed to afford the C=C coupled products (31 examples) in good to excellent yields (36–87%). DFT studies have been undertaken to elucidate the mechanism for this alkenylation reaction.
