The present paper describes the 1, 1-dichlorocyclopropane formation from highly electron-deficient carbon-carbon double bonds conjugated, in the main, with two cyano groups by allowing to react with trichloroacetic acid. β-Trichloromethylation was indicated in some cases. Path of the 1, 1-dichlorocyclopropane formation is presumed not to involve dichlorocarbene, but β-trichloromethylated intermediate.
