N-Oxides of 1,1,1-Tris(pyrid-2-yl)ethane

Abstract Herein we report the synthesis of a new class of pyridine-N-oxide compounds, namely: 1,1,1-tris(pyrid-2-yl)ethane N-oxide, 1,1,1-tris(pyrid-2-yl)ethane N,N'-dioxide and 1,1,1-tris(pyrid-2-yl)ethane N,N', N”-trioxide. The Mono-N-oxide is formed by treatment of the parent pyridine compound with hydrogen peroxide in acetic acid at 100 ˚C. On the other hand, treating the corresponding pyridine with m-chloroperbenzoic (m-CPBA) acid in chloroform at reflux led to a mixture of di and tri-N-oxide products.
