Richter cyclization and co-cyclization reactions of triazene-masked diazonium ions

The conventional Richter cyclization involves diazotization of 2-alkynylanilines with HX (aq) (X = Br or Cl) and NaNO2, followed by spontaneous ring closure to give a mixture of 4-halocinnoline and 4-cinnolinone products. The different products

Cinnolines and Pyrazolopyridazines. - Novel Synthetic and Mechanistic Aspects of the Richter Reaction

The thermal cyclization of 2-alkynylbenzenediazonium salts 2 known as the Richter reaction and leading, as described in the literature, only to 4-hydroxycinnolines 6 has been studied.A new probable route to these compounds involving intermediate formation
