Banerjee et al  uses copper(III) periodate and copper(III) tellurate as oxidants for oxidative decarboxylation of [alpha]-hydroxyacids.
The reagent is easily prepared by heating Cu(II) salt with potassium persulphate as an oxidizing agent in presence of a bulky ligand like tellurate or iodate in alkaline medium of potassium hydroxide [3,8,26,27].
2], and 5% sodium hydroxide to dissolve and precipitate the tellurium as calcium tellurate
1995) Frankhawthorneite, a unique HCP framework structure of a cupric tellurate
Scalenohedral calcite crystals were observed in vugs on top of penroseite and with clausthalite and chalcopyrite associated with overgrowths of tellurates
Behind the Iron Curtain this trip was represented as a "lecture tour," and Martin's specimens, including benitoite and newly descfibed tellurites and tellurates
, were "samples" for the "lectures.
