Abstract:

Diaryl ditelluride derivatives bearing different functional groups were prepared with the aim to study their ability to interact through chalcogen bonding (ChB). Rectangular Te₄ and triangular Te₃ motifs were observed in the solid-state as a result of intermolecular Te⋅⋅⋅Te ChB. In solution, the use of the very sensitive ¹²⁵Te, ¹⁷O NMR analyses as well as ¹⁹F−¹H HOESY allowed unambiguous detection of a Te⋅⋅⋅O chalcogen bond between the diaryl ditellurides and phosphine oxides.
