We have recently synthesized and characterized new stable arenediazonium camphorsulfonate salts. However, the purification was the problem associated with this methodology. Recovering from this problem we have adapted the same method which we have developed for the preparation of arenediazonium tosylate salts which includes the diazotization of aromatic amines in the presence of p-TsOH by using a sodium-free polymer-supported diazotization agent1 and successfully synthesized a series of pure and stable arenediazonium camphorsulfonate salts. Diazotization of wide range of aromatic amines was easily carried out by stirring of a mixture of appropriate amine, CSA and the reagent ‘Resin-NO2-’ at room temperature in AcOH. Prepared arenediazonium camphorsulfonate salts have easily isolated even in a dry state and show excellent thermal stability. Thus they can be kept safely even for a long time until a subsequent transformation is ready.
