Dehydrogenative silylation of primary and secondary amines with triphenylsilane was catalyzed by ytterbium-imine complexes, [Yb(η2-Ph2CNAr)(hmpa)n], to give aminosilanes in good yields. In the reaction with diphenyl- and p

Ru3(CO)12 has been shown to catalyse the coupling of silanes with thiols, alcohols and amines with turnover number (TON) and turnover frequency (TOF) of up to 200 and 50 h-1 at 80 °C. IR, NMR and mass spectroscopic studies have identified a ruthenium dimer complex, [Ru(CO)4(SiEt3)]2 as a likely resting state of the catalyst. A mechanism involving this complex has been proposed for the silicon-thiol coupling process.

Phenylmagnesium bromide reacts with triphenylsilyl azide (in contrast to organyl azides) in two parallel reactions. One type of reaction is the substitution of the azide group by the magnesium-bound organyl residue. The other is the formation of the adduct, (C6H5)3SiN3·C6H5MgBr, containing an N-diazonium group. At higher temperatures the adduct decomposes by elimination of N2 to give (C6H5)3SiN(C6H5)MgBr. The same type of reaction generally occurs when silyl azicles R3SiN3 react with arylmagnesium halides R′MgHal. The hydrolysis of the silyl amide leads to amines R′NH2. In connection with this the formation of R3SiNR′(MgHal) by the reaction of R3SiN3 with R′MgHal (=R′Hal + Mg) provides a simple procedure to prepare aromatic amines from aromatic halides.
