An improved synthesis of dialkylcyclopropenones

Article abstract of DOI:10.1080/00397910008087222

Dialkylcyclopropenones are formed in high yields when alkynes are treated with chloroform-butyllithium in THF at - 78 °C followed by acidic hydrolysis of the dichlorocyclopropene intermediates at low temperatures.
