ChemInform Abstract: Catalytic Activity of Reusable Nickel Oxide Nanoparticles in the Synthesis of Spirooxindoles.

Abstract

Spirooxindoles. -The reaction between malonitrile, isatins, and 1,3-dicarbonyl compounds including 1,3-cyclohexadione, dimedone, and 4-hydroxycoumarine provides indoline derivatives in high yields. The catalyst is reused in five consecutive cycles with only slight loss of its activity. -(NASSERI*, M. A.; KAMALI, F.; ZAKERINASAB, B.; RSC Adv. 5 (2015) 34, 26517-26520, http://dx.
