Abstract New three-component reaction was developed via one-pot strategy for the synthesis of functionalized 3,3′-disubstituted oxindoles and spirooxindole through the reaction among isatin, malononitrile, and acetone/indole/nitromethane/acetylacetone/dimedone in ethanol as solvent without base. It was observed that all the mixed ligand transition metal complexes with triphenylphosphine worked as the
