Reaction of a series of aldehydes and ketones with the potassium salt of N,O-bis(trimethylsilyl)hydroxylamine (2) gave high yields of the corresponding oximate anion 5. This anion, formed in a Peterson-type reaction, could be protonated to the oxime 7 or trapped in situ with a variety of electrophiles to give O-substituted oxime derivatives.8

In the presence of a catalytic amount of an antimony(V) salt generated from antimony(V) chloride and silver antimonate, the Beckmann rearrangement of several ketoxime trimethylsilyl ethers proceeds smoothly to give the corresponding amides or lactams in good yields.
