The reaction of sodium bis(trimethylsilyl)amide with bromobenzene gave a mixture of N,N-bis-(trimethylsilyl)aniline and N,2-bis(trimethylsilyl)aniline, the latter being a rearrangement product formed via 1,3-migration of trimethylsilylgroup from the nitrogen atom to the ortho-carbon atom in the benzene ring.

dithiasuccinoyl (Dts)-amine, serves as a readily removable amino protecting group for building blocks used in syntheses of peptides, glycopeptides, and PNA; it is also useful as a masked isocyanate and (inversely) as a sulfurization reagent for trivalent phosphorus. Bis(chlorocarbonyl)disulfane, the two-sulfur analogue of succinyl chloride, has been envisioned as a reagent for facile single-step elaboration of the

[reaction: see text]. Symmetric azoxy arenes were successfully prepared in one step from 2 equiv of the corresponding nitroarenes by use of sodium bis(trimethylsilyl)amide as the deoxygenating agents in THF at 150 degrees C in a sealed tube.

Arsenic trichloride reacts with silicon-nitrogen and silicon-sulphur compounds to give the chlorosilane and corresponding arsenic-nitrogen or arsenic-sulphur compound. Phenylarsenic dichloride reacts in a similar way with silicon-sulphur compounds but not with silicon-nitrogen derivatives.
Five types of reactions between (dimethylalumino)(trimethylsilyl)methylamine Me2AlNMeSiMe3 and carbonylcompounds (ketones, esters and amides) were found to occur, depending on the structure of the carbonylcompounds. Among others two new interesting compounds, 4-(dimethylamino)-4-(methylamino)-3-buten-2-one CH3COCHC(NHMe)NMe2 from acetamide and N, O-dimethylacylimidatetetramethyldialumoxane
