SYNTHESIS OF ETHYNYLIDENE CYCLOPENTANES BY A CYCLISATION CATALYZED BY THE SIMULTANEOUS PRESENCE OF PALLADIUM (0) AND COPPER (I)

Ethynylidene cyclopentanes 3 can be formed in 35-71percent yield from the reaction of the enolates of compounds such as δ-acetylenic malonates with 1-halogeno-1-alkynes.This reaction requires catalysis by both palladium (0) and copper (I) species.
