摘要: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 Beta-Bromoethyl Group Is Replaced First. Low-Temperature H-1 NMR Spectroscopy Showed That The Prepared Seven-Membered Heterocycle Is Conformationally Flexible.
