Polydimethyl-co-methyl(3-aminopropyl)siloxanes differing in the content of amino groups and molecular weight were synthesized by two pathways, namely, by hydrosilylation of oligodimethyl-co-methylhydrоsiloxane with N-(trimethylsilyl)allylamine (TMSAA) and by copolymerization of octamethylcyclotetrasiloxane with methyl(3-aminopropyl)cyclosiloxanes. The colloid-chemical properties of the synthesized oligomers were studied. The oligosiloxanes possess high surface activity and can reduce the interfacial tension in the interface surfactant solution in toluene–water to 6.7–4.2 mJ m2. Aggregatively stable polystyrene suspensions with particle of 0.5 and 0.8 μm in diameter were obtained in the presence of the synthesized oligomers.
Dianion aggregates derived from lithiation of N-silyl allylamine
Williard, Paul G.,Jacobson, Madeleine A.
, p. 2753 - 2755 (2000)
Three different N-silyl-protected allylamines, i.e., N-TMS, N-TBDMS, and N-TIPS allylamine, were lihtiated by reaction with excess n-butyllithium. Crystallization of the resulting dianions and X-ray structure determination yields three uniquely different aggregates.
IMPROVED PROCESS FOR PRODUCING BIS-(AMINOALKYL)-POLYSILOXANES

Page/Page column 16-17, (2008/12/07)
Bis(aminoalkyl)siloxane dimers or oligomers are prepared by a process utilizing hydrosilation of an olefinic amine with tetraorganodisiloxane or with bis(dialkylhydrogen)siloxane oligomers to generate high purity bis(aminoalkyl)disiloxane or bis(aminoalkyl)siloxane oligomers at high conversion yield, which may then be subsequently equilibrated to higher molecular weight bis(aminoalkyl)polysiloxanes.
N-silyl-tethered radical cyclizations: a new synthesis of gamma-amino alcohols.
Blaszykowski, Christophe,Dhimane, Anne-Lise,Fensterbank, Louis,Malacria, Max

[reaction: see text] Various allylic and propargylic amines bearing a protecting group (PG) have been employed in N-silyl-tethered radical cyclizations. The resulting silapyrrolidine adducts could be smoothly oxidized, creating access to gamma-amino alcoh
Novel method for preparing bis(trimethylsilyl) amines via treatment with trimethylsilylamines and methyl iodide
Hamada, Yoshitaka,Yamamoto, Yasushi,Shimizu, Hideaki
, p. 1 - 6 (2007/10/03)
A convenient method for the synthesis of N,N-bis(trimethylsilyl)alkylamines has been reported. N-(Trimethylsilyl)diethylamine incorporated with a stoichiometric amount of methyl iodide was effective to convert primary amines, especially aromatic amines, and their monotrimethylsilyl derivatives into the corresponding N,N-bis(trimethylsilyl)amine derivatives in high yields. In the case of N-trimethylsilyl derivatives of aliphatic primary amines, a half-amount of silylamines served as a silylation agent against another half-amount of silylamines in the presence of 0.5 equivalent of methyl iodide to give N,N-bis(trimethylsilyl)alkylamines in good yield. Allyl iodide, allyl bromide and benzyl bromide were also effective to promote the silylation activity of silylamines.

2-Methyl-1-trimethylsilyl-Δ3-1,2-azaboroline (1), synthesized from LiCH=CH-CH2-NLi and CH3BBr2 can be transformed to 2-methyl-Δ3-1,2-azaboroline (2) by elimination of the trimethylsilyl group with etheral HCl. 2 dimerises at room temperature via N -> B-coordination to 2. 1 and 2 react with Fe(CO)5 to the azaborolinyl complexes di-μ-carbonyl-biscarbonyl-(2-methyl-1-trimethylsilyl-η-1,2-azaborolinyl)iron>(Fe - Fe) (3) and di-μ-carbonyl-bis(Fe - Fe) (4), resp.The IR, 1H-NMR, 11B-NMR, and mass spectra of the compounds are discussed.
