Article abstract of DOI:10.1016/0040-4039(91)80215-R

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.
