Acyloxyferrole complexes are easily prepared by the reaction of alkynes and Fe3(CO)12/Et3N in THF, which upon reaction with Br2 in dichloromethane at −78 °C give the corresponding cyclobutenediones in 60−90% yields. The acyloxyferrole complex prepared using diphenylacetylene and acetyl chloride was characterized by single-crystal X-ray analysis.
