- Abstract
In order to synthesize the first seven-membered N-triflylazasilacycloalkane the reaction of triflamide with (2-bromoethyl)(3-chloropropyl)dimethylsilane was studied. Depending on the reaction conditions bis(3-chloropropyl)tetramethyldisiloxane, 3-trifluoromethylsulfonylaminopropyl(3-chloropropyl)-tetramethyldisiloxane, (2-triflamidoethyl)(3-chloropropyl)dimethylsilane, bis(3-triflamidopropyl)tetramethyldisiloxane, and the target 4,4-dimethyl-1-(trifluoromethylsulfonyl)-1,4-azasilepane have been isolated. In all cases the halogen atom in the β-bromoethyl group is replaced first. Low-temperature H NMR spectroscopy showed that the prepared seven-membered heterocycle is conformationally flexible.
