Abstract

Sodium percarbonate was found to be an ideal and efficient oxygen source for the oxidation of tertiary nitrogen compounds to N-oxides in excellent yields in presence of various rhenium-based catalysts under mild reaction conditions.

Key words

rhenium - solid oxidants - sodium percarbonate - oxidation - N-oxides
