Herein reported is a nickel-catalyzed α-1,3-dienylation reaction of 1,3-dicarbonyl compounds with substituted propargylic (e.g., but-2-ynyl) carbonates. The propargyl unit changes into a 1,3-dienyl unit, which is incorporated at the α-position of the 1,3-dicarbonyl compounds.
Key words
nickel - 1,3-diene - malonate - propargylic carbonate - C–C bond formation
