azoxy and aniline derivatives. The reaction leading to anilines has been investigated in detail. Two different processes have been identified, both initiated by the condensation between the nitrosoarene intermediate (the first product of the reduction reaction) and the product of oxidation of the solvent. The imino derivative thus formed (ArNCH–COR) may either undergo hydrolysis (to aniline) or form
2-Methylthio-substituted 1,4-enediones, obtained from readily available aryl methyl ketones, were reacted with primary or secondary amines to afford the desired 1,4-diaryl-2-aminobut-2-ene-1,4-diones in excellent yields with high Z/E-stereoselectivity. (C) 2012 Elsevier Ltd. All rights reserved.
