Electrochemical Dearomative ipso -Cyclization of Indolyl-ynones: A Direct Access to Trifluoromethyl/Selenyl-Spirooxindoles

-annulation, and oxidation reactions. The method represents an uncommon example of the construction of spirocyclic oxindoles with good substrate scope. Additionally, the efficacy of this strategy was revealed by synthetic transformations of the product.
