Abstract: There were studied series of activated enolethers (alkoxymethylene derivatives of malonic or 3-oxobutanoic acids derivatives of general formula R—O—CH=C(R1, R2) where R1 = R2/ R1 ≠ R2 (R1, R2 = CO2CH3, CO2CH2CH3, COCH3, CN) with N,N-dimethylhydrazine. They smoothly provided products of nucleophilic vinylic substitution reaction — dimethyl hydrazinyl methylene derivatives of malonic or 3-oxobutanoic acids (enhydrazines), respectively from 20 minutes to 2 hours at room temperature.

Keywords: N,N-dimethylhydrazine, enolethers, nucleophilic vinylic substitution reaction, enhydrazines
