Abstract
Abstract The di-tert-butyl(di-tert-butylphenylsilyl)iminosilane R2Si=NR′ (R = CMe3, R′ = Si(CMe3)2Ph) (1) reacts with compounds having acidic protons to give insertion products. Treatment of 1 with ethanol leads to the silyl ether (R2SiOC2H5NHR) (2). In reaction with HCl the aminochlorosilane (R2SiClNHR′) (3) is formed. Compound 3 is also obtained by hydrolysis of the corresponding lithium derivative. Compound 1 reacts with acetone (4) and 2,3-dimethyl-1,3-butadiene (5) in an ene reaction to give the isopropenyloxysilylamine R2SiOC(CH2)Me-NHR′ (4), and the 4,5-dimethylene-1-aza-2-silahexane (R2Si(C6H9)-NHR′ (5). Compound 1 combines with 2,6-diethylphenylazide in a [2 + 3]-cycloaddition to give the tetraazasilacyclopentene R2SiNR′(NR″)N2 (R″ =2,6-C6H3(C2H5)2) (6). Treatment of 1 with THF leads to the THF adduct R2Si(THF)NR′ (7). The latter reacts with 1,4-dihydroxybenzene by insertion into the OH bonds to give the 1,4-bis(1-oxa-3-aza-2,4-disilabutyl)benzene 1,4-C6H4(OSiR2-NHR′)2 (8). With divinyloxyethane the bis(1-aza-2-silacyclobutyloxy)ethane 1,2-C2H4(OCHCH2SiR2NR′)2 (9) is formed in a [2 + 2]-cycloaddition. The crystal structures of 5 and 6 are described
