supporting information, p. 13736 - 13739 (2021/12/27)
The application of diaryltelluronium cations as chalcogen bonding organocatalysts was investigated for the Ritter-like reaction using time-course NMR analysis. The resistance to water of dicationic oligotelluroxanes differed depending on the oligomer chai
The highly selective metal-free oxidation of sulfides, tellurides and phosphines using sodium bromate in the presence of recyclable ionic liquid [bmim]HSO4, at 80°C

The metal-free oxidation of sulfides to sulfones using sodium bromate (NaBrO3) in [bmim]HSO4:H2O (3:1, v/v) at 80°C is reported. Phenylalkyl, phenylbenzyl, diaryl and heteroaryl sulfides were transformed to the corresponding sulfones. Aryl tellurides and phosphines were oxidised to the corresponding telluroxides and phosphine oxides. All the reactions proceeded smoothly and gave high yields in 20-55 min. The ionic liquid [bmim]HSO4 was easily recovered and recycled.
Aqueous sodium hypochlorite mediated chemoselective oxidation of chalcogenides to monoxides and dioxides by microwave exposure

experimental part, p. 906 - 909 (2011/01/08)
A solvent-free, rapid, and highly selective oxidation of sulfides, selenides, and tellurides (chalcogenides) to the corresponding monoxides (sulfoxides, selenoxides, and telluroxides) or the corresponding dioxides (sulfones, selenones, and tellurones) has been developed using aqueous sodium hypochlorite on solid supports by exposure to microwave. Chemoselectivity and quantitative yields have been attained in most cases.

The oxygen atom insertion of nitrogen monoxide or O2 molecule between tellurium atoms by various chemical oxidation methods of diaryl telluride to produce dicationic bis(diaryltellurium(IV)) oxide is described.
Insertion of an oxygen atom between tellurium atoms upon oxidation of a diaryl telluride with NOBF4 or (CF3SO2)2O/O2: Dicationic bis[diaryltellurium(IV)] oxide

, p. 984 - 986 (2007/10/03)
NO and O2 molecules are the source of the oxygen atom for dicationic μ-oxo(diaryltellurium) dimers 2 (X = BF4/-, CF3SO3/-), which form upon chemical oxidation of 1 with NOBF4 (method A) or (CF3SO2)2O/O2 [method B, Eq. (a)]. The fate of the nitrogen atom of the oxidizing agent NOBF4 remains uncertain at this stage.
SYNTHESIS, STRUCTURE, AND PROPERTIES OF COMPOUNDS WITH A CHALCOGEN-NITROGEN BOND. II. DIARYL-N-BENZYLSULFONYLTELLURIMIDES

, p. 2210 - 2216 (2007/10/02)
The IR, UV, and PMR spectra of a series of diaryl-N-benzylsulfonyltellurimides were investigated.These compounds are bipolar and have a considerable positive charge on the tellurium atom.
