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 π symmetry, as well as σ 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.
