A highly efficient and green synthesis of novel, potentially medicinally important oxindole derivatives has been developed using a fully recoverable heterogeneous copper ferrite nanocatalyst in water as a green solvent. The catalyst is magnetically separable and recyclable up to the fourth run without significant loss of activity. The products were obtained in high yields and purities via an easy workup procedure.

A highly efficient and green method for the synthesis of new 2-(3-(dicyanomethyl)-2-oxoindolin-3-ylthio)acetic acids is described using magnetically recoverable and reusable CuFe2O4 nanoparticles. A wide variety of aryl isatylidene malononitrils underwent Micheal addition with thioacids to afford novel 2-(3-(dicyanomethyl)-2- oxoindolin-3-ylthio)acetic acids in good to excellent yields. The reaction protocol is operationally simple and mild. Moreover, water as solvent makes the reaction procedure eco-friendly and economically viable. All products were characterized by NMR and IR spectroscopies.
