Synthesis and Characterization of a Novel Crowned Schiff Base Ligand Linked to Ionic Liquid and Application of Its Mn(III) Complex in the Epoxidation of Olefins

A new Schiff base ligand bound to ionic liquid and crown ether was synthesized and complexed with Mn (III) metal. Manganese complex was used in the vicinity of oxone oxidant and the absence of an axial base in water-chloroform biphasic oxidation to oxidize different alkenes, the corresponding epoxides were obtained with 70-96% yields. The lowest efficiency is related to alkenes with electron-withdrawing groups.

Automated summary

A new Schiff base ligand complexed with Mn (III) metal was synthesized and used with oxone oxidant in water-chloroform biphasic oxidation. The complex was able to oxidize different alkenes to corresponding epoxides with yields of 70-96%, with the lowest efficiency observed for alkenes with electron-withdrawing groups.
