title: Spirocyclic boronium ions: precursors to persistent neutral radicals.
abstract: Spirocyclic boronium ions based on the 9-bora-9,10-dihydroanthracene scaffold and substituted 2,2'-bipyridyl ligands have been prepared; these cations are shown to be convenient starting materials for the preparation of neutral radicals with significant spin density on boron.
