A new, convenient, efficient, and cost-effective one-pot synthesis of 1Hphenanthro[9,10]imidazol-2-yl from phenanthraquinone and aldehydes, using sulfuric acidimmobilized on silica as catalyst is described. The present methodology offers severaladvantages such as excellent yields, simple procedure, shorter reaction times, the use ofinexpensive reagents, easy recovery and eco-friendly. In addition to these, 2-alkylphenanthrimidazole is obtained from triethyl orthoesters in good yields.
