The reaction of 4-methylene-substituted 1-phenyl-3-methyl-5-pyrazolones with potassium cyanide and sodium dimethylamide leads to the formation of the cyanovinyl and dimethylaminovinyl carbanions respectively.The potassium salt of the cyanovinyl carbanion enters readily into carboxylation, cyanoethylation, alkylation and acylation.
