(Chemical Equation Presented) The synthesis of dipyridopyrazole and pyridopyrazolopyrazine derivatives - both of which incorporate a 3-aryl moiety - can be achieved in moderate yields by intramolecular radical arylation of pyridinium N-aminides using tris(trimethylsilyl)silane and azobisisobutyronitrile. Improved results were obtained on using Pd direct arylation in conjunction with microwave irradiation. A preliminary study into the fluorescent properties of the target compounds is also reported.
