The synthesis and structural characterization of dicationic
selenium
and tellurium analogues of the carbodiphosphorane and triphosphenium
families of compounds are reported. These complexes, [Ch(dppe)][OTf]2 [Ch = Se, Te; dppe = 1,2-bis(diphenylphosphino)ethane; OTf
= trifluoromethanesulfonate], are formed using [Ch]2+ reagents
via a ligand-exchange protocol and represent extremely rare examples
of homoleptic pnictogen → chalcogen coordination complexes.
The corresponding arsenic compounds were also prepared, [Ch(dpAse)][OTf]2 [Ch = Se, Te; dpAse = 1,2-bis(diphenylarsino)ethane], exhibiting
the first instance of an arsenic → chalcogen dative bond. The
electronic structures of these unique compounds were determined and
compared to previously reported chalcogen dications.
