Abstract

Abstract. The synthesis of trialkylsilyl-bis (triflu0rmethane-sulfony1) imides 3 is described. Compounds 3 with bulky trialkylsilyl groups 3a, b only exist in the silatautomeric form 3a', b'under usual conditions, 3c in theN-trimethylsilyl structure. Despite of the bulky silyl substituents in3a', b'their reactivity is higher than that of trimethylsilyltriflate. Alcohols, carbonyl compounds, nitroalkanes and carboxylic acid esters are silylated in good yields, ...
