Synthesis of 5-Substituted 1H-Tetrazoles from Nitriles in the Presence of Heterogeneous Catalyst
PublicationTetrazoles are five-membered heterocyclic compounds containing in their rings four nitrogen atoms. They have wide applications as corrosion inhibitors, analytical reagents, high-energy materials and gas generating compositions. Tetrazoles also play important role in coordination chemistry as ligands and in medicinal chemistry as metabolically stable surrogates for carboxylic acids. In recent years, investigation of new method of...

Practical Method for the Preparation of 2,2-Dimethyl-5- {aryl[(hetero)aryl]methyl}-1,3-dioxane-4,6-diones: Synthesis and Mechanistic Study
PublicationAn efficient practical synthetic procedure has been developed for the synthesis of 2,2-dimethyl-5-{aryl[(hetero)aryl]methyl}- 1,3-dioxane-4,6-diones through Friedel–Crafts alkylation. The scope and limitation of the reaction of 2,2-dimethyl-5-arylidene-1,3-dioxane- 4,6-diones with π-excess aromatic systems have been delineated.
