Efficiency of the NiL complex towards catalysing epoxidation of olefins in presence of various oxidants vi z., NaOCI , KHSO₅, H₂O₂ ,pyridine N-oxide (PyO), <i style="mso-bidi-font-style:normal">t</i>-BuOOH, etc. , has been examined and it is found that the NiL complex can effectively catalyze the epoxidation of olefins in presence of NaOCI and KHSO₅.</span>
