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
