From Alkyl Tellurium Trifluorides and Cesium Fluoride 

When a mixture of cesium fluoride and pentafluoroethyl tellurium trifluoride was heated for one hour at 100°, cesium penlqfluor( ethyltetrafluorotellurate(IV) was obtained.  

From Organo Tellurium Trihalides and Onium Flalides 

RJM = diethylammonium, pyrolidinium, tctraalkylammonium, tetraphenylphosphonium, triphenylalkylphosphonium, tctraphenylarsonium, triphcnylsulfonium, triphenylsclenonium, triphenyltelluronium, diphenyliodonium 

Onium Aryltetrahalotellurates(rV) [Organic Medium] 3 mmol of the aryl tellurium trihalide are dissolved in dry methanol or ethanol, a solution of 3 mmol of the onium halide in the same alcohol is added dropwise at 20°, and the precipitated product is filtered yield 85%.
