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.

The preparation and chromium(II)-induced reduction of twelve α-acetylenic ketones are reported.In general only trans-olefinic products were observed; the yields ranged from 40-84percent.A particular advantage of this protocol is its selectivity, thereby permitting use with a wide variety of functionalities.
