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. Copyright (C) 1996 Elsevier Science Ltd
