title: Gold(I) mediated rearrangement of [7]-helicene to give a benzo[cd]pyrenium cation embedded in a chiral framework.
abstract: The facile gold-mediated skeletal rearrangement of [7]-helicene into a cationic polyaromatic hydrocarbon is described. We report in-depth studies on the structure and aromaticity of this novel stable cation and propose a mechanism for its formation.
