In this regard, different polyalkynylated, polyalkenylated and polyarylated pyridine, pyrazine and naphthyridine derivatives were synthesized. Moreover, photophysical and electrochemical investigations of polyalkynylated compounds were carried out. In addition, various N-phenyl diarylpyrrols were synthesized by “ligand-free” palladium-catalyzed C–H activation. A probable mechanism was proposed.
