title: A Cyclotriborane Dianion and the Triboron Cation: "Light Ends" of the Hückel Rule.
abstract: The lightest synthetically accessible Hückel π-aromatic system, a triboracyclopropenyl dianion bearing three dicyclohexylamino groups, has been obtained by reduction of dicyclohexylaminoboron dichloride and structurally characterized as the dimeric disodium salt (see scheme; Cy=cyclohexyl, DME=1,2-dimethoxyethane).
