A new and facile method for the preparation of arenetelurinic mixed anhydrides is described from diaryl ditellurides and phenyliodine (III) dicarboxylates. Hydrolysis of the arenetellurinic mixed anhydrides gives arenetellurinic anhydrides and a one-pot p

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.

The disproportionation reaction of diaryl ditellurides with sodium hydroxide under phase transfer conditions at room temperature is described for the first time.The phase transfer catalyst used is 2HT-75, a trade name for a mixture of dialkyldimethylammonium chlorides.The intermediates aryl tellurolates react "in situ" with alkyl halides to give the corresponding alkyl aryl tellurides (ArTeR) in 52-72percent yield.The following compounds were prepared: Ar = C6H5, R = CH3(CH2)3CH2,(CH3)2CHCH2CH2, (CH3)2CHCH2, CH3CHBrCH2CH2, CH3(CH2)8CH2, C6H5CH2, ClCH2, C6H5CH2CH2, CH2=CHCH2, C6H5CH=CHCH2, C6H5SeCH2, ; Ar = p-CH3C6H4, R = CH3(CH2)2CH2; Ar = p-CH3OC6H4, R = CH3(CH2)2CH2; Ar = p-C2H5OC6H4, R = CH3(CH2)2CH2; Ar = 2-naphthyl, R = CH3(CH2)2CH2.
