Phenox azine, 10-ethyl-, and 10-phenylphenoxazine are metalated by n- butyllithium to give what probably are 4-substituted carboxylic acids. Attempts to prove the structures by interconversion of the acids were not successful. 10- Ethylphenoxazine-8-carboxylic acid and 10-(4-carboxyphenyl)-phenoxnzine were prepared by a halogen-metal interconversion reaction, which established these structures.
