Direct dearomative C3-functionalization of indoles provided access to privileged scaffolds by an umpolung strategy. Against all odds, C3-indolium intermediates could be generated from NH-indoles under operationally simple conditions with triflic acid at room temperature to promote intra- and intermolecular C3-regioselective hydroarylation. DFT studies suggest that these cationic or dicationic intermediates

The scope and limitations are described for a powerful new method to access indoles bearing a quaternary center at C-3 using easily accessible bisaryl λ3-iodanes and a cheap organic base.
