From Dichloroamino Tellurium Pentafluoride

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

Chloro(trimethylsilyl)amino Tellurium Pentafluoride3 5.14 g (16.7 mmol) of dichloroamino tellurium pentafluoride, prepared from trimethylsilylamino tellurium pentafluoride and chlorine fluoride3, are dissolved in 10 m/ of fluorotrichloromethane, 2.75 g (18 mmol) of bromotrimethylsilane are added dropwise under protection from moisture, and the resultant solution is slirred 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. -3070.007 torr.
