Deoxygenation of quinoxaline and phenazine <i>N</i>‐oxides by catalytic transfer reduction and by iodide in the presence of pyridine/sulfur trioxide complex

Abstract

Abstract Quinoxaline and phenazine di‐ N ‐oxides are deoxygenated under mild conditions by catalytic transfer reduction or by treatment with sodium iodide in the presence of pyridine/sulfur trioxide complex.
