Synthesis of tetra- and octa-aurated heteroaryl complexes towards probing aromatic indoliums

Abstract

Polymetalated aromatic compounds are challenging synthetic goals. Here, the authors describe the synthesis of tetra-aurated indole and octa-aurated benzodipyrrole complexes, in which incorporation of the aurated substituents at the nitrogen atoms leads to hyperconjugative aromaticity in the five-membered rings.
