title: Ligand-stabilized chalcogen dications.
abstract: Chalcogen-transfer reagents? The bonding in the dicationic rings C(2)N(2)E(2+) (see picture) differs from that in N-heterocyclic carbenes and their isovalent p-block analogues in accommodating a lone pair of electrons with pi symmetry, as well as sigma symmetry, on the chalcogen center. The labile electrophilic chalcogenium dications (E(2+)) are potentially versatile chalcogen-transfer reagents in reactions with a variety of inorganic and organic substrates.
