Base-promoted rearrangement of siloxyammonium salts: a new method of dealkylation of tertiary amines via their N-oxides
Abstract
Siloxyammonium salts prepared from tertiary amine N-oxides and trialkylsilyl trifluoromethanesulphonate undergo rearrangement in the presence of strong bases to give α-siloxyamines, which can be converted into secondary amine derivatives.
