ABSTRACT:
N-Methoxy derivatives of the sterically hindered amines 4-hydroxy-2,2,6,6-tetramethylpiperidine and 2,2,6,6-tetramethyl-4-piperidone are prepared from the corresponding N-oxyl hindered amine by combining hydrogen peroxide and a peroxide-decomposing transition metal salt in the presence of dimethyl sulfoxide.
