A General Uncatalyzed Method for the Synthesis ofO-Silylated Oximes
摘要:
Aldoximes and ketoximes were smoothly and efficiently O-silylated at room temperature with diverse chlorosilanes such as TMSCl, TBSCl, or TIPSCl in dichloromethane or THF, using imidazole as a-base to trap the generated hydrochloric acid.

Aromatic O-triisopropylsilyl ketoximes were efficiently rearranged to cyclic and acyclic aniline derivatives on reduction with BF3-ethearate /borane. The bulk of the substituents on the silicon atom, the size of the aliphatic ring, and the presence of alkoxy substituents on the aryl group all play an important role in the aniline.
