## Abstract The reaction of phenylacetylenes 4a–h with copper(I) acetate (5) and TCNE (tetracyanoethylene) in THF/acetonitrile gave 4‐phenyl‐1‐buten‐3‐yne‐1,1,2‐tricarbonitriles 6a–h. 4i did not react to give 6i. The phenylacetylenes 4b–i were prepared by a two‐step synthesis starting from the corr
