The ¹²⁵Te Chemical Shift of Diphenyl Ditelluride: Chasing Conformers over a Flat Energy Surface

Molecules, 2019
The interest in diphenyl ditelluride (Ph2Te2) is related to its strict analogy to diphenyl diselenide (Ph2Se2), whose capacity to reduce organic peroxides is largely exploited in catalysis and green chemistry.

Supramolecular Chalcogen‐Bonded Shape Memory Actuators

Angewandte Chemie
Abstract Supramolecular liquid crystal elastomers (LCEs) incorporating chalcogen bonds (ChBs) have been synthesized and investigated for shape memory and actuation properties. LCEs featuring strong Se⋯N ChBs (−40 to −43 kJ mol −1 ) exhibit both shape memory effects (SME) and

Catalytic Sulfur‐Atom Transfer Enabled by a Bis(disulfide) Titanium Complex

Angewandte Chemie International Edition, EarlyView.
Multi‐electron transformations with titanium are underexplored due to limited access to low‐valent precursors. The four‐electron activation of elemental sulfur by a Ti(IV) complex yields a rare titanium bis(disulfide) complex, enabling the efficient catalytic synthesis of isothiocyanates from isonitriles under mild conditions.
