Interaction of diazomethane with bis(trimethylsilylamino)mercury gives the polymeric explosive solid. 

The reaction of (trimethylsilylamino)(trifluoromethyl) methylene-malonate (1532) and /erf-butyl hypochlorite or N./V-dibromobenzene-sulfonamide in benzene afforded 2-halogen derivatives of the malonate (1538) in 92% and 85% yields, respectively (81ZOR439). 

While the chemistry of the cyclodiphosph(III)azanes is now well founded, few compounds are known in which the P—N skeleton is extended exo to the PjNj-ring. Such compounds would provide examples of multidentate ligands, and present interesting comparisons with trimethylsilylamino-derivatives, where the bulky silyl-groups are known to kinetically stabilise phosph(III)azenes such as (MCjSO NP ... 

Although free from the formally oxidising anions present in the two groups below, a few of these compoimds show instability. These are cA-Bis(trimethylsilylamino )tellurium tetrafluoride, 2615 Pentaamminechlororuthenium chloride, 4137... 

N-Tritylamino acids. Direct reaction of trityl chloride with amino acids provides N-trityl derivatives in low yield. A superior route to these derivatives involves reaction of trimethylsilyl esters of N-trimethylsilylamino acids with trityl chloride in refluxing chloroform, which provides the N-protected amino acids in 88-92% yield. Trimethylsilyl-protected hydroxyl or thiol groups are not cleaved under these conditions.1...

Equimolar amounts (0.1 mol) of tellurium hexafluoride and bis[trimethylsilyl]amine formed explosive cis-bis[trimethylsilylamino] tellurium tetrafluoride when heated at 60° in a steel cylinder3. The compound is a colorless crystalline material that can be sublimed at 40°/0.001 torr. 

Equimolar amounts of tellurium hexafluoride and bis[trimethylsilyl]amine reacted at 20° in a stainless steel vessel and gave, after 12 h, trimethylsilylamino tellurium pentafluoride in almost quantitative yield1-3. 

Trimethylsilylamino Tellurium Pentafluoride 16.1 g (0.1 mol) of bis[trimethylsilyl]amine are placed in a 250 ml stainless steel vessel which is then cooled to —196°. 31.4 g (0.13 mol) of tellurium hexafluoride are condensed into the vessel which is then sealed, warmed to 20°, and stirred at this temperature for 12 h. The resultant mixture is distilled in a glass apparatus and the fraction boiling at 58°/12 torr is collected yield 31 g (100%) m.p. 9° b.p. 58°/12 torr. 

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. 

Trimethylsilylamino tellurium pentafluoride treated with carbonyl difluoride at 60° produced carbonylamino tellurium pentafluoride7 . 

Carbonylamino Tellurium Pentafluoride3 3.1 g (10 mmol) of trimethylsilylamino tellurium pentafluoride are placed in a 100 ml stainless steel cylinder which is then cooled. 1.98 g (30 mmol) of carbonyl difluoride are condensed into the cylinder which is then closed and heated at 60° for 15 h. The resultant mixture is distilled under a dynamic vacuum through —78° and —196° traps. The contents of the —196° trap are pumped...

Also, N-trimethylsilyl-N -phenylcarbonylcarbodiimide is obtained from PhCONHCN and trimethylchlorosilane." Bis(trimethylsilyl)amine or 2,4,6-tris(trimethylsilylamino)-l,3,5-triazine react with dicyanodiamide to give bis(trimethylsilyl)carbodiimide. ... 

As an X-ray structure determination of 2,4-bis(iV-lithium/butylamido)-l,3-di-/butyl-cyc/o-disilazane (4a), obtained as large colorless crystals from an npentane solution failed for still unkno vn reasons, the compound was treated with excess chlorotrimethylsilane. Depending on the reaction temperature and the solvent used - either refluxing THF with a subsequent exchange for npentane or only npentane at room temperature - cis- (4b) or trans-2,4-bis(/butyl-trimethylsilylamino)-l,3-di-/butyl-c5 c/o-disilazane (4c) is formed in a nearly quantitative yield.
