Oxidation to Diorgano Tellurium Dioxides

Diorgano tellurium oxides are reported to be slowly oxidized by atmospheric oxygen to high-melting diorgano tellurium dioxides . This oxidation can be carried out in a controlled manner with sodium periodate in aqueous methanoF [Pg.647]

Diorgano tellurium oxides react with hydrohalic acids by regenerating the diorgano tellurium dihalides, the common starting materials for the preparation of diorgano tellurium oxides. The reactions with hydrochloric acid, hydrobromic acid , and hydroiodic acid, therefore, are not of synthetic importance. The reaction with hydrofluoric acid , however, is a convenient way of preparing diorgano tellurium difluorides. [Pg.647]

Irgolic Organo Tellurium Compounds with 2 Te—C Bonds or 1 Te=C Bond [Pg.648]

Addition of diaryl tellurium oxides to excess acyl chlorides quantitatively produced diaryl tellurium dichlorides [Pg.648]

Diorgano tellurium oxides react with nitric and perchloric acid producing diorgano tellurium hydroxide perchlorates diperchlorates hydroxide nitrates or dinitrates . [Pg.648]
