Air-stable aryl derivatives of pentafluoroorthotellurate

We report on two different sets of air-stable derivatives of pentafluoroorthotellurate containing fluorinated and non-fluorinated aryl groups. The acid cis-PhTeF(4)OH was obtained in gram scale and further transformed to Ag[cis-PhTeF(4)O], which was used as a cis-PhTeF(4)O transfer reagent to obtain...

description We report on two different sets of air-stable derivatives of pentafluoroorthotellurate containing fluorinated and non-fluorinated aryl groups. The acid cis-PhTeF(4)OH was obtained in gram scale and further transformed to Ag[cis-PhTeF(4)O], which was used as a cis-PhTeF(4)O transfer reagent to obtain [PPh(4)][cis-PhTeF(4)O]. Furthermore, the synthesis of trans-(C(6)F(5))(2)TeF(3)OH was achieved by a selective hydrolysis of trans-(C(6)F(5))(2)TeF(4) in the presence of KF and subsequent protonation by aHF. Quantum-chemical calculations show a higher acidity and robustness against fluoride abstraction for trans-(C(6)F(5))(2)TeF(3)OH compared to cis-PhTeF(4)OH.
