Reactivity of Nitroalkyl Anions Addition to Substituted Benzylidenecyanoacetates: Electrophilicity Parameters and Free Energy Relationships

Autor: Nejeh Dhahri, Taoufik Boubaker, K. Azaiez

Publikováno v: International Journal of Chemical Kinetics. 49:847-858

The kinetics of the reactions of benzylidenecyanoacetates 1a–d (X = H, Me, OMe, and NMe2) with nitroalkyl anions 2a–c have been studied in aqueous solution at 20°C. The second-order rate constants are used to evaluate the electrophilicity parame

Kinetics of alkaline hydrolysis of p-substituted benzylidenemalononitriles in 50% aqueous acetonitrile: substituent effects and quantification of the electrophilic reactivity

Autor: Nejeh Dhahri, Régis Goumont, Boubaker Taoufik

Publikováno v: Journal of Physical Organic Chemistry. 27:484-489

The rate constants of the reaction of p-X-substituted benzylidenemalononitriles 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h with hydroxide ion were measured in 50% water–50% acetonitrile at 20 °C. The experimental kinetic data reveal that the points pertaining
