The reaction of the diorganotellurium oxides R2TeO (R ≤ Ph, p-MeOC6H4, p-Me2NC6H4) with phenol and o-nitrophenol produces diorganotellurium hydroxy phenolates, R2Te(OH)OPh (1, R ≤ Ph; 2, R ≤ p-MeOC6H4; 3, R ≤ p-Me2NC6H4), diorganotellurium bis(phenolates) R2Te(OPh)2 (4, R ≤ Ph; 5, R ≤ p-MeOC6H4; 6, R ≤ p-Me2NC6H 4), tetraorganoditelluroxane bis(o-nitrophenolates), (R?O)R 2TeOTeR2(OR?) (7, R ≤ p-MeOC6H4; 8, R ≤ p-Me2NC6H4; R? ≤ o-NO 2C6H4), and a hexaphenyltritelluroxane bis(o-nitrophenolate) (R?O)Ph2TeOTePh2OTePh 2(OR?) (9, R? ≤ o-NO2C6H4), respectively. The redistribution reactions of R2Te(OPh)2 (4, R ≤ Ph; 5, R ≤ p-MeOC6H4; 6, R ≤ p-Me 2NC6H4) with the corresponding diorganotellurium oxides R2TeO and diorganotellurium dichlorides R2TeCl2 (R ≤ Ph, p-MeOC6H4, p-Me2NC6H4) give rise to the formation of moisture sensitive tetraorganoditelluroxane bis(phenolates) (PhO)R 2TeOTeR2(OPh) (10, R ≤ Ph; 11, R ≤ p-MeOC 6H4; 12, R ≤ p-Me2NC6H 4) and diorganotellurium chloro phenolates, R2Te(Cl)OPh (13, R ≤ Ph; 14, R ≤ p-MeOC6H4; 15, R ≤ p-Me 2NC6H4), respectively. The reaction of the diorganotellurium oxides R2TeO with the corresponding diorganotellurium dichlorides R2TeCl2 (R ≤ Ph, p-MeOC6H4, p-Me2NC6H4) affords tetraorganoditelluroxane dichlorides ClR2TeOTeR2Cl (16, R ≤ Ph; 17, R ≤ p-MeOC6H4; 18, R ≤ p-Me2NC6H4) as air-stable solid materials. The reactivity of 1?18 can be rationalized by the kinetic lability of the Te?O and Te?Cl bonds. Compounds 1?18 have been characterized by solution and solid-state 125Te NMR spectroscopy and 2, 4, 6, 7, 9, 17, and 18 have also been analyzed by X-ray crystallography. CSIRO 2008.
