α-Siloxy amines, which were easily prepared by “silicon Polonovski reaction” of tertiary amine N-oxides with trialkylsilyl trifluoromethanesulfonate, were treated with various nucleophiles to give the corresponding α-functionalized tertiary amines in moderate to good yields. This new method has the advantage that it enables the α-substitution of amines not only by alkyl groups but also by alkenyl and

α-Siloxyamines obtained from tertiaryaminesvia their N-oxides react with Grignard reagents and trialkylaluminums to afford newtertiaryamines having an α-substituent derived from the organometallics.
