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.

Podol'skii, A. V.,Khonina, T. G.,Lyampasova, T. P.,Kodess, M. I.
, p. 1476 - 1480 (2007/10/03)
Polychloromethylation of Me3SiCl, Me2PhSiCl, Me2SiCl2, and MePhSiCl2 in the system magnesium-chloroform-THF has been studies under mild conditions (in the temperature renge 60 -65 deg C), and a scheme of formation of the main and by-products has been proposed.
