Phenylalkyl tellurides

Aqueous Phase One‐Electron Reduction of Sulfonium, Selenonium and Telluronium Salts

“…[34] Diphenyl methyl telluronium tetrafluoroborate [36] and ethyl methyl phenyl telluronium tetrafluoroborate [37] were prepared by literature methods. The following materials were prepared in analogy with published procedures (alkyl aryl selenides [38] and tellurides [39] ) and were used as reference compounds in the GC analyses: cyclohexyl phenyl selenide, [40] cyclohexyl phenyl telluride, [41] ethyl phenyl sulfide, [42] ethyl phenyl selenide, [43] ethyl phenyl telluride, [44] methyl phenyl selenide [45] and methyl phenyl telluride. [44] Preparation GC analyses were performed on a Varian 3400 GC fitted with a capillary Rescom SE 54 column and a flame ionization detector.…”

[44] Preparation GC analyses were performed on a Varian 3400 GC fitted with a capillary Rescom SE 54 column and a flame ionization detector. Calibration curves were made for benzene, methyl phenyl telluride, diphenyl sulfide, diphenyl selenide and diphenyl telluride with pentadecane as internal standard.…”

[44] Preparation of Onium Tetrafluoroborate Salts. Typical Procedure: Diphenyl Methyl Selenonium Tetrafluoroborate (4): AgBF 4 (0.86 g, 98 %, 4.30 mmol) was slowly added to a mixture of diphenyl selenide (1.00 g, 4.30 mmol) and methyl iodide (6.10 g, 43 mmol) under N 2 at ambient temperature.…”

Samarium (II) diiodide‐induced reductive cleavage of SeSe and TeTe bond in diphenyl diselenide and ditelluride leading to a samarium phenylselenolate and tellurolate: Preparation of unsymmetrical alkylphenyl selenides and tellurides

“…Evaporation of the solvent left a yellow oil that was subjected to preparative TLC on silica gel (petroleum ether as eluent). The phenylalkyl selenides [2, 3, 6a] and tellurides [22] prepared have been reported.…”

Synthesis of organochalcogen compounds in basic reducing systems

“…[36][37][38] In this solvent, ditellurides were reduced with lithium metal with subse quent synthesis of alkyl aryl tellurides. [36][37][38] In this solvent, ditellurides were reduced with lithium metal with subse quent synthesis of alkyl aryl tellurides.…”
