Reactions of Trialkylsilyl Trifluoromethanesulfonates, V. - Synthesis and Reactions of N,N-Bis(trialkylsiloxy)-1-alken-1-aminesNitroalkanes 1 react with trialkylsilyl triflates 2 in the presence of triethylamine to yield N,N-bis(trialkylsiloxy)-1-alken-1-amines (nitrosoalkene acetals) 4, which are rearranged to give 2-(trialkylsiloxy)oxime O-trialkylsilyl ethers 6 by heating or by Lewis acids. 2-Amino-aldoxime O-trialkylsilyl ethers 8 or 2-aminoaldoximes 9 are obtained by reaction of amines 7 with the acetals 4.
Notes:
Nitroalkane 1 reagieren mit Trialkylsilyl-triflaten 2 in Gegenwart von Triethylamin zu N,N-Bis(trialkylsiloxy)-1-alken-1-aminen (Nitrosoalken-acetale) 4, die thermisch oder durch Lewis-Säuren in 2-(Trialkylsiloxy)oxim-O-trialkylsilylether 6 umgelagert werden. Durch Umsetzung der Acetale 4 mit Aminen 7 erhält man 2-Aminoaldoxim-O-trialkylsilylether 8 bzw. 2-Aminoaldoxime 9.
