WebChemical Reactions of Diazonium Salts. Reactions which involve retention of the diazo group. This article deals with the reactions which involve the replacement of nitrogen. Diazonium group is a good leaving group. They are substituted by other groups such as Cl –, Br –, CN –, and OH – which easily displace nitrogen from the aromatic ring. WebJun 15, 2016 · I thought of this reaction: C u X 2 + + 2 K I C u I X 2 + 2 K X +. But since C u I X 2 doesn't exist, the I X − ions must reduce C u X 2 + to C u I and simultaneously get oxidised to I X 2 and thus it will proceed the following reaction:-. 2 C u X 2 + + 4 K I 2 C u …
