experimental part, p. 180 - 184 (2010/03/01)
Novel boron compounds, a series of 4-hydroxy-5,6-dihydroborauracil and 4-hydroxy-5,6-dihydroborathymine derivatives containing various substituents at 3-, 5- and 6-positions, is presented. The spectroscopic properties, along with analyses of NMR-controlled boron compound-alcohol and boron compound-amine interactions, proves the existence of sp3-hybridized, stable B,B-bis-methoxy-5,6-dihydroborauracils and pyridine-/n-butylamine-5,6-dihydroborauracils ate-complexes in solution.
Rhodium-catalyzed silylation and intramolecular arylation of nitriles via the silicon-assisted cleavage of carbon-cyano bonds

A rhodium-catalyzed silylation reaction of carbon - cyano bonds using disilane has been developed. Under these catalytic conditions, carbon-cyano bonds in aryl, alkenyl, allyl, and benzyl cyanides bearing a variety of functional groups can be silylated. The observation of an enamine side product in the silylation of benzyl cyanides and related stoichiometric studies indicate that the carbon-cyano bond cleavage proceeds through the deinsertion of silyl isocyanide from η2-iminoacyl complex B. Knowledge gained from these studies has led to the development of a new intramolecular biaryl coupling reaction in which aryl cyanides and aryl chlorides are cross-coupled.
Chemically Labile Stannylene-Nitrogen Bonds. The Chemoselective and Stereoselective Synthesis of N,N-Bis(trimethylsilyl)enamines and N,N-Dialkylenamines
Burnell-Curty, Cynthia,Roskamp, Eric J.
, p. 5063 - 5064 (2007/10/02)
The chemoselective reaction of Sn2 with primary aldehydes leads to the stereoselective synthesis of trans-N,N-bis(trimethylsilyl)enamines.More reactive Sn(NR2)2 (R = Et, iPr, or piperidine) can be generated in situ and then treated with aldehydes or ketones to give trans enamines.
CONTRIBUTIONS TO THE CHEMISTRY OF ORGANIC SILICON-NITROGEN-COMPOUNDS, I. SYNTHESIS OF N,N-BIS-(TRIMETHYLSILYL)AMINES
Schorr, Manfred,Schmitt, Wilfried
, p. 25 - 36 (2007/10/02)
The preparation of N,N-bis-(trimethylsilyl)amines 1 has been investigated.Three convenient methods are reported: A, Transfer of (catalytically) activated Tms-groups to amines starting from N-silylated carbonamides, B, silylation of amines with trimethylsilylchloride 5/NEt3 in the presence of TiCl4, C, silylation of primary amines 4 or mono-(trimethylsilyl)amines 16 with CF3SO3 Tms/NEt3 or TmsI/NEt3.Methods A and B are limited to the silylation of (ar)alkylamines which have no branched α-position. Key words: N,N-bis-(trimethylsilyl)amines; N,N-bis-silylamines; N-silylcarbonamides.
