Abstract

Reaction between CF3TeTeCF3 and (CH3)3SnH in Et2O provides (CH3)3SnTeCF3 in 75% yield. This is a good starting material for the preparation of TeCF2 and its cyclic dimer, because pyrolysis of (CH3)3SnTeCF3 at 280° (10-3 Torr) yields TeCF2 in 60% yield. On warming from -196° to 20°, TeCF2 dimerizes quantitatively to the corresponding tetrafluoro-l,3-ditelluretane.
