SANDMEYER REACTION

SANDMEYER REACTION

• The DIAZONIUM (C₆H₅N₂Cl) is prepared by treating ice cold solution of ANILINE (C₆H₅NH₂) in excess of dilute HCl (Hydrochloric acid) with an aqueous solution of NaNO₂ at low temperature (0-5)°C and the reaction is known as DIAZOTIZATION REACTION. 
• BROMO and CHLORO ALKANES can be prepared by treating a freshly prepared DIAZONIUM SALT with CUPPEROUS BROMIDE or CUPPEROUS CHLORIDE and this reaction is called as SANDMEYER REACTION.
