Synthesis and Characterization of Fluorinated Hypervalent Tellurium Derivatives

Synthesis and Characterization of Fluorinated Hypervalent Tellurium Derivatives
Ewa Pietrasiak, Antonio Togni
The synthesis of tellurium derivatives bearing fluorinated groups, similar in structure to their hypervalent iodine congeners, is reported. Thus, a series of CF3, CF2H, and C6F5 aryltellurium(II) species bearing various functional groups interacting with the Te atom was obtained. The installation of the various fluorinated groups relies on the use of the corresponding trimethylsilyl precursors. The hypervalent nature of the products is discussed on the basis of their NMR spectroscopic and X-ray crystallographic characterization.
