One-Step Synthesis of Azo Compounds from Nitroaromatics and Anilines. — A general method for the uncatalyzed coupling to produce symmetric and unsymmetric aromatic azo compounds is described. The reaction presumably proceeds through for-mation of the corresponding nitrosobenzene [cf. (IV)] from the nitroarene. — (ZHAO, R.; TAN, C.; XIE, Y.; GAO, C.; LIU, H.; JIANG*, Y.; Tetrahedron Lett. 52 (2011) 29, 3805-3809, http://dx.doi.org/10.1016/j.tetlet.2011.05.054 ; Dep.
