Amino Tellurium Pentafluorides

Amino tellurium pentafluorides are thermally rather unstable, moisture-sensitive compounds. 

---

Dichloroamino tellurium pentafluoride and bromotrimethylsilane formed chloro(tr t-methylsilyl)amino tellurium pentafluoride, as a yellow, moisture-sensitive liquid that decomposes slowly at room temperature to trimethylfluorosilane1. 

Chloro(trimethylsilyl)amino Tellurium Pentafluoride 5.14 g (16.7 mmol) of dichloroamino tellurium pentafluoride, prepared from trimethylsilylamino tellurium pentafluoride and chlorine fluoride, are dissolved in 10 ml of fluorotrichloromethane, 2.75 g (18 mmol) of bromotrimethylsilane are added dropwise rmder protection from moisture, and the resultant solution is stirred at 20° for 2 h. The components of the mixture are separated by several trap-to-trap distillations with traps at —30°, —78°,and —136° yield 3.17 g (55%) b.p. -30°/0.007 torr. 

Mercury bis[pentafluorotelluro(trifluoromethyl)amide] reacted with elemental halogens and interhalogens to yield halo(trifluoromethyl)amino tellurium pentafluoride The less electronegative halogens of the interhalogens Join the amide-nitrogen atom.
