Ultrasound-assisted synthesis of symmetrical biaryls by palladium-catalyzed detelluration of 1,2-diarylditellanes

An ultrasound-assisted synthesis of functionalized symmetrical biaryls with electron-withdrawing or electron-donating substituents is described and illustrated by the palladium-catalyzed detelluration of 1,2-diarylditellanes. This procedure offers easy access to symmetrical biaryls in short reaction time and the products are achieved in good to excellent yields.

Tellurides Bearing Sulfonamides as Novel Inhibitors of Leishmanial Carbonic Anhydrase with Potent Antileishmanial Activity

We report for the first time a novel series of tellurides bearing sulfonamide as selective and potent inhibitors of the β-class carbonic anhydrase (CA; EC 4.2.1.1) enzyme expressed in Leishmania donovani protozoa. Such derivatives showed high activity against axenic amastigotes, and among them, compound 5g (4-(((3,4,5-trimethoxyphenyl)tellanyl)methyl)benzenesulfonamide) showed an IC50 of 0.02 μM being highly selective for the parasites over THP-1 cells with a selectivity index of 300. The in vitro and in vivo toxicity experiments showed compound 5g to possess a safe profile and thus paving the way for tellurium-containing compounds as novel drug entities.

Sunlight oxidation of alkyl aryl tellurides to the corresponding carbonyl compounds: A new carbonyl precursor

Alkyl aryl tellurides were efficiently transformed to the corresponding carbonyl compounds by photo-oxidation with sunlight without affecting various functional groups in the alkyl moiety. The tellurides can be used as a new carbonyl precursor, and the photolysis can be conducted without special equipment for light sources.

Mild reduction of tellurium(IV) and selenium(IV) compounds by sodium ascorbate

Sodium ascorbate was found to mildly reduce organyltellurium trihalides to diorganyl ditellurides, organylselenium trihalides to diorganyl diselenides, diorganyltellurium dihalides and oxides to diorganyl tellurides and diorganylselenium dihalides and oxides to diorganyl selenides.

Method for preparing aromatic and olefinic organoselenium and organotellurium compounds

This invention constitutes a method of preparing molecular and supramolecular aromatic organic telluride, ditelluride, diselenide and selenide compounds from aromatic halogen compounds which are unactivated toward nucleophilic substitution. The method involves the reaction of an aromatic halide with an alkali metal telluride, ditelluride, selenide or diselenide reagent formed from chalcogen and alkali metal trialkylborohydride to yield the corresponding molecular or polymeric aromatic telluride, ditelluride, selenide or diselenide. Further, the alkali metal chalcogenide reagent prepared from alkali metal trialkylborohydrides may also be used to synthesize molecular and polymeric olefinic tellurides and selenides from olefinic halides unactivated toward nucleophilic substitution.

SYNTHESIS AND REACTIONS OF 2-NAPHTHYLTELLURIUM TRICHLORIDE

TeCl4 and naphtalene, when heated to 110 deg C in the abscence of a solvent, yielded 2-naphtyltellurium trichloride (2), which on treatment with degassed Raney Ni afforded 2,2'-binaphthyl in excellent yield.Reaction of 2 with propene and cis-2-butene produced the corresponding 1:1 adducts, which however could not be coupled to 2-(2-chloroalkyl)naphthalenes with this reagent.
