Abstract
![]()
Phenoxazines, in
particular N-arylated phenoxazines, represent
an increasingly important scaffold in the material sciences. Moreover,
the oxygen-gas-mediated dehydrogenative phenochalcogenazination concept
of phenols has been developed and exemplified for X = sulfur and recently
for X = selenium and tellurium. The smallest chalcogen, X = oxygen,
is herein exemplified with various functional groups under a likewise
trivial oxygen atmosphere.

Abstract
N-Substituted phenoxazines and related aza analogs have been prepared from N-acetylated aryloxy anilides by transition-metal-free, base-catalyzed cyclization reactions. In the presence of a mixture of 10 mol % of N,N'-dimethylethylenediamine (DMEDA) and 2 equiv of K(2)CO(3) in toluene at 135 °C the products are obtained in high yields.
