diazonium การใช้

• diazonium dye fast blue to demonstrate alkaline phosphatase enzyme activity directly.
• It couples with various aryl diazonium salts to give diazo dyes.
• NOHSO 4 is useful in organic chemistry to prepare diazonium salts from amines.
• In this process, paper or film is coated with a diazonium salt.
• Triazenes have been used as " in situ " diazonium source.
• Aromatic iodides may be prepared via a diazonium salt in the Sandmeyer reaction.
• Diazonium salts are light sensitive and break down under near UV or violet light.
• It is also possible to functionalize silicon wafers with diazonium salts forming an aryl monolayer.
• Aryl diazonium perchlorates, such as nitrobenzenediazonium perchlorate, have been used to initiate explosives.
• Triazenes decompose in the presence of protonating or alkylating agents into quaternary amines and diazonium salts.
• In other organic research he showed that diazonium compounds undergo 2 + 4 cycloaddition to dienes.
• The modification of carbon nanotubes with aryl diazonium salts was studied first by Tour et al.
• To make the dyes, acetoacetanilides are coupled to diazonium salts, " azo coupling ".
• Anilines and naphthylamines form more stable diazonium salts, which can be isolated in the crystalline form.
• Diazonium salts undergo a variety of useful transformations involving replacement of the N 2 group with anions.
• The other steps look OK, so long as the methoxide will not also substitute the diazonium.
• It is often preferred that the diazonium salt remain in solutions, but they do tend to supersaturate.
• Hg ( II ) can be alkylated by treatment with diazonium salts in the presence of copper metal.
• "' Benzenediazonium chloride "'is an organic compound with the diazonium cation and chloride.
• In another example, the synthesis of cinnoline was accomplished by Richter reaction of triazene-masked diazonium ion.
