This method enabled the activation of C sp2 ‐H bonds, resulting in the formation of C sp2 ‐C sp2 single bonds and the generation of highly substituted derivatives of ( E )‐2‐(2‐oxoindolin‐3‐ylidene)‐1‐aryl‐3‐substituted‐propane‐1,3‐diones and ( E )‐3‐oxo‐2‐(2‐oxoindolin‐3‐ylidene)‐3‐substituted‐propanoates. The synthesized non‐toxic Fe 2 O 3 nano‐material was meticulously characterized through FT‐IR, powdered XRD, HRTEM, EDX, BET, and ICP‐MS analyses. This heterogeneous catalyst can be conveniently recovered with a magnetic field and reused in subsequent reactions. This method offers excellent functional‐group tolerance, efficient substrate yield in less time, simple workup, and a recyclable catalyst. 10.1002/aoc.7821 http://onlinelibrary.wiley.com/termsAndConditions#vor |
