amines with acyl halides and haloformates gave the corresponding amides and carbamates in moderate to good yields, respectively. Treatment of α-siloxy amines with acetic acid resulted in a direct dealkylation to free secondary amines. Fluoride induced alkylation of α-siloxy amines using alkyl halides as electrophiles leading to tertiaryamines was also examined and demonstrated to be a new transalkylation

Siloxyammoniumsalts prepared from tertiaryamineN-oxides and trialkylsilyl trifluoromethanesulphonate undergo rearrangement in the presence of strong bases to give α-siloxyamines, which can be converted into secondary amine derivatives.
