Iodoarenes synthesis by iodination or substitution

Coupling reactions of diazonium ions. In the substitution reactions above, the nitrogen in the diazonium ion is lost. In the rest of the reactions on this page, the nitrogen is retained and used to make a bridge between two benzene rings. The reaction with phenol. Phenol is dissolved in sodium hydroxide solution to give a solution of sodium phenoxide.

In the rest of the reactions on this page, the nitrogen is retained and used to make a bridge between two benzene rings.The reaction with phenolPhenol is dissolved in sodium hydroxide solution to give a solution of sodium phenoxide.The solution is cooled in ice, and cold benzenediazonium chloride solution is added.

Reaction of ketene dithioacetal with salicylaldehyde Tetrabutylammonium fluoride also catalyzes the cyclization of diethyl.

Chemical Reactivity - Michigan State University

There is a reaction between the diazonium ion and the phenoxide ion and a yellow-orange solution or precipitate is formed.The product is one of the simplest of what are known as , in which two benzene rings are linked by a nitrogen bridge.
