Ssr synthesis technique with ball milling

Apr 01, 2021

The implementation of solvent-free ball milling was very rare in organic synthesis. However, this technique was attracting attention because of its low cost, simplicity, and good results in pure form without the need for further purification. This technique was also environment friendly. Therefore, this ball grinding technique was superior to
