3-Aryl-1-tetrazol-5-yltriazenes, bench-stable arenediazonium ion synthons: synthesis of biaryls and aryl halides
Abstract
3-Aryl-1 -tetrazol-5-yltriazenes have been used as a bench-stable source of diazonium ions for the synthesis of substituted biaryls, aryl halides (iodides, bromides, and chlorides) and azo dyes. The dediazoniation process when induced by trihalogenoacetic acid or acetic acid did not involve free radicals.
