On the stereochemistry of β-elimination of β-silyl azides
摘要:
Fluoride-mediated elimination of syn and anti beta-silyl azides was shown to afford the corresponding (Z)- and (E)-olefins, respectively, demonstrating that beta-elimination of beta-silyl azides is stereospecifically anti. (C) 2003 Elsevier Ltd. All rights reserved.

Three methods have been employed in the synthesis of 2-trialkylsilylaziridines. Firstly, reacting α-chloro-α-silyl carbanions with imines. Secondly, from the corresponding vinylsilane, via addition of bromoazide to give the 1-bromo-2-azide, followed by reduction. Finally, by the addition of organoazides to vinylsilanes using thermochemical and photochemical conditions. Using these three strategies a range of substitution patterns have been achieved.
