The chromium carbonyl carbenecomplexes bearing an acetoxyl group and a phenyl substituent were found to react smoothly with acetylene compounds to produce naphthoquinone derivatives in good yields after oxidation. This cycloaddition reaction proceeded regioselectively and several naphthoquinones were prepared selectively from the complex and unsymmetrical acetylenes.
