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 K2CO3 in toluene at 135 degrees C the products are obtained in high yields.

A secondary battery that includes a positive electrode active material layer, which is mainly composed of an organic compound having a multi-electron system, on a surface of a positive electrode current collector. The surface of the positive electrode active material layer is covered by an ion-conducting thin film that selectively transmits lithium ions. A positive electrode is composed of the positive electrode current collector, the positive electrode active material layer, and the ion-conducting thin film.
