A new method for the diazotization of aromatic amines in sheet a non- aqueous system is presented.
A Green aniline Procedure for the sheet Diazotization– Iodination of Aromatic Amines. Introduction of NO into a closed air- free reactor containing an aqueous solution of aniline in nitric acid resulted in no detectable diazotization. Sinalizar sheet por conteúdo inapropriado. This demonstrates the necessity phenolic of the oxidizing agent. The process is a modification of the known Knoevenagel' s method consists of treating solutions dispersions of amine sulphates in ethylene glycol diazotization with glycol nitrite.
Most functional groups can survive this technique, as long as they are stable in the presence of dilute acid. Phenol is the organic compound containing benzene ring bonded to a hydroxyl group. A milder more general reaction is the diazotization of an arylamine phenolic ( a derivative of aniline, C 6 H 5 NH 2) to give a diazonium salt which hydrolyzes to a phenol.
