The temperature range of 0-5°C is crucial in diazotization because it helps maintain the stability of the diazonium salt formed during the reaction. At lower temperatures, the reaction is more controlled, reducing the risk of side reactions and decomposition of the diazonium compound, which can occur at higher temperatures. This ensures a higher yield and purity of the desired product in subsequent coupling reactions. Additionally, the cold environment minimizes the risk of unwanted reactions with other functional groups that may be present in the substrate.
