Description 313-324
Efficient tandem three component method has been demonstrated for the synthesis of substituted tetrazoles under mild reaction conditions using copper catalysis. Green solvent DMSO has been utilized and the reaction has been carried out at room temperature which establishes that our method is green synthetic approach. Variety of substrates readily undergo the optimized reaction conditions to provide their respective target products in good to excellent yields. In addition we have observed regioselective compounds depending on the substituents of phenyl ring. All the reactions are rapid, facile and are accomplished at room temperature. The reactions are of general application, clean and efficient. Furthermore we have confirmed that no other by-products could be identified during our experimental reaction process. In addition, C-N cross-coupling have been developed with phenyltetrazoleamines and aryl iodide under moderate reaction conditions.
