Rezumat

The reactivity of the 1,3-dipolar cycloadditions of C,N-diphenylnitrone with acrylonitrile in different microemulsion systems has been investigated. The effect of the nature of surfactant (cationic, anionic), a component of water- and oil-borne microemulsions, on the rate of this reaction have been studied. The electrostatically attractive character of cetyltrimethylammonium bromide, a cationic surfactant, would bring the reactants closer to each other; hence, a rate enhancement would ensue, particularly within the water-rich zone. Besides, the fact that acrylonitrile played a dual role, as a component of the microemulsion and a dipolarphile in the cycloaddition reaction, made the work-up advantageously sound. Additionally, the increase in reagents molar ratio was found to promote higher reactivity..
