Article abstract of DOI:10.1016/S0040-4039(96)02282-4

The reaction between acetylenes and cyclopropylcarbene-chromium complexes in hexane affords exclusively cyclopentadienone derivatives in good yield, which are readily hydrolyzed to cyclopentenediones. The analogous reaction in 50:50 water dioxane affords cis disubstituted cyclopentenones.
