A convenient method for the synthesis of O-tert-butyldimethylsilyl oximes
Aromatic, aliphatic, cyclic and acyclic O-tert-butyldimethylsilyl oximes were prepared in 77 to 85% yield by the reaction of the corresponding aldoximes and ketoximes with tert-butyldimethylchlorosilane (TBSCI) using imidazole/DMF system.

A New Synthesis of Oxime Derivatives from Carbonyl Compounds and N,O-Bis(trimethylsilyl)hydroxylamine
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.
