An improved synthesis of dialkylcyclopropenones
Netland, Kjetil Andreas,Gundersen, Lise-Lotte,Rise, Frode
, p. 1767 - 1777 (2007/10/03)
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.
