Significance
A three-component, flexible and stereocontrolled synthesis of unsymmetrically substituted 3-(diarylmethylene)indolinones is presented. The reaction involves Pd/Cu-catalyzed sequential Sonogashira reaction, carbopalladation, C-H activation and, overall, three C-C bond-formation processes. The electronic properties of the substituents on the aryl and heteroaryl halides did not play a significant role, as evidenced by the yields of the reactions.
