Realization of a silica supported chiral catalyst with very high efficiency is showed

What is it about?

We report on a thermally and temporally robust covalent monolayer of (salen)Mn(III) molecules on silica functionalized substrates that resulted in an active heterogeneous catalyst for enantioselective epoxidation of 6-ciano-2,2-dimethyl-chromene

Why is it important?

Given the widespread importance of chiral epoxides in chemical, biochemical and agricultural fields, an efficient synthesis that avoids wasteful use of the catalyst and assures its total recovery and reuse and high turnover values is highly desirable.
