Abstract
Methoxyallene reacts with carbon monoxide in the PdCl2–CuCl2–NaHCO3 (NaHCO3/NaOAc) system in MeOH to afford methyl 2-(dimethoxymethyl)acrylate and 2-chloro-3,3-dimethoxyprop-1-ene; the third product, 2-chloro-1-methoxy-2-propenyl acetate, appears when NaHCO3–NaOAc is used as a buffer component.
