In this article, a mild and highly efficacious synthetic route has been developed for the synthesis of spiro[indoline-3,9 '-xanthene]trione and spiro[chromene-4,3 '-indoline]-3-carbonitrile derivatives using graphene oxide-supported dicationic ionic liquid (DIL@GO) as a heterogeneous catalyst in aqueous media. Targeted spiro[indoline-3,9 '-xanthene]trione derivatives were synthesized via one-pot condensation of substituted isatins and 1,3-diketone compounds (1,3-cyclohexanedione/dimedone), and spiro[chromene-4,3 '-indoline]-3-carbonitrile derivatives were synthesized via one-pot reaction of substituted isatins, malononitrile, and enolizable C-H-activated compounds (2-hydroxynaphthalene-1,4-dione/dimedone). The DIL@GO catalyst demonstrated outstanding catalytic capabilities in all the tested reactions and yielded excellent isolated yields of the final products within a short reaction time. Additionally, the heterogeneous nature of the catalyst facilitates catalyst separation through centrifugation, and its reusability up to five successive reaction cycles with retention in activity makes this methodology more advantageous and environmentally benign.
