Palladium-catalyzed three-component synthesis of 3-(diarylmethylene)oxindoles through a domino Sonogashira/carbopalladation/C-H activation/C-C bond-forming sequence

[Pd(PPh3)4]/Cul served as an efficient catalyst for the reaction of three readily available starting materials to give 3-(diarylmethylene)indolin-2-ones, e.g., I, through a sequence of intermol. Sonogashira reaction/intermol. carbopalladation/C-H activation/C-C bond formation. Three C-C bonds were thereby formed as a result of three distinct catalytic cycles with one catalyst.
