- Synthesis and properties of tellurinic anhydride-tellurone adducts
-
The synthesis and characterization of stable tellurinic anhydride-tellurone adducts are reported. Treatment of aryltellurinic anhydride with diaryl tellurone gave pentacyclotelluroxane consisting of two molecules each of the starting tellurium oxides. The bulky aromatic substituents attached to the tellurium atoms efficiently prevent further aggregation and enable full characterization using multinuclear (1H, 13C, and 125Te) NMR and IR spectroscopy as well as elemental analysis. For (TipTe)4(Tip2Te)2O10 (3TT, Tip = 2,4,6-triisopropylphenyl), the molecular structure was unambiguously determined by an X-ray crystallographic analysis. To estimate the dissociation energies of the tellurinic anhydride-tellurone adducts, density functional theory calculations were performed, and it was found that the adducts are highly stabilized by forming a four di-μ-oxo bridge structure.

Reaction of Te-aryl benzenecarbotelluroates of the type ArCOTeAr' (Ar=phenyl p-tolyl, p-bromophenyl; Ar'=phenyl, p-methoxyphenyl) with methyl iodide was found to give symmetrical telluronium salts, (1+)I(1-) in good yields.The reactivity of one of these benzene carbotelluroates towards halogens was also examined.

- REACTIONS OF ACETYLACETONE WITH ORGANOTELLURIUM (IV) CHLORIDES-C1 BONDED ACETYLACETONATES OF TELLURIUM(IV)
-
The reactions of acetylacetone (AcAc) with ArTeCl3 (I), Ar2TeCl2 (II) and Ar3TeCl (III) (where Ar = phenyl, 4-hydroxyphenyl, 4-methoxyphenyl, 4-ethoxyphenyl, 3-methyl-4-hydroxyphenyl and 3,4-dihydroxyphenyl) have been investigated.The I gives ArTe(C5H7O2)Cl2 (IV) type derivatives but II and III do not react even on prolonged refluxing in the presence of anhydrous AlCl3.The structural features of the new acetonylacetone derivatives (IV) have been explored by IR, PMR, and CMR spectroscopy.The effect of phenyl ring substituents on the keto-enol tautomerism of IVhas been found to be minor.The bond formation between Te and C1 of AcAc and intramolecular secondary interaction between the oxygen of AcAc and Te have been inferred from spectral data.

- COMPOUNDS WITH A TELLURIUM-NITROGEN BOND. N-(ARYLSULFONYL)ARENETELLURINIMIDOYL HALIDES
-
In the reaction of diaryl ditellurides and aryltellurenyl chlorides with N,N-dihalogenoarenesulfonamides N-(arylsulfonyl)arenetellurinimidoyl halides are formed.The same compounds are obtained in the reaction of aryltellurium trihalides with disilylated arenesulfonamides.The reactions of the acid halides with trimethylsilylmorpholine leads to the formation of the morpholides of N-(arylsulfonyl)arenetellurinimidic acids, and the reaction with hydrogen chloride, water, and dimedone is accompanied by cleavage of the tellurium-nitrogen bond with the formation of aryltellurium trihalides, arenetellurinyl halides, and telluronium ylides.
