Oxidation of secondary and tertiary amines by a solid base catalyst

Choudary BM, Reddy CV, Prakash BV, Bharathi B, Kantam ML

A novel recyclable protocol is developed for the oxidation of secondary and tertiary amines to nitrones and amine N-oxides, respectively, by Mg-Al-O'Bu hydrotalcite (HT-O'Bu) catalyst, and benzonitrile as an additive in methanol using 30% hydrogen peroxide at a faster rate in quantitative yields for the first time.
