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