A convenient synthesis of secondary hydroxylamines
O'Neil, Ian A.,Cleator, Ed,Tapolczay, David J.
, p. 8247 - 8249 (2007/10/03)
The oxidation of a range of β-cyanoethyl tertiary amines with mCPBA gives the corresponding N-oxides, which can be isolated or undergo Cope-elimination to give secondary hydroxylamines in excellent yield.
