An unusual de-nitro reduction of 2-substituted-4-nitroquinolines
摘要:
The treatment of a variety of 2-substituted-4-nitroquinolines with Sn in the presence of concentrated hydrochloric acid in ethanol at 70 degrees C for 2-4 h afforded unusual de-nitro products 2-substituted-quinolines in good yields. (c) 2006 Elsevier Ltd. All rights reserved.
A process for producing a biaryl compound, characterized by reacting an arylhydrazine compound, hydrogen peroxide and an aryl compound. When the reaction is conducted in the presence of a given metal or a compound of the metal or in the presence of a metal oxide obtained by reacting the given metal or a compound of the metal with hydrogen peroxide, then the yield of the biaryl compound is improved.
