Design of a highly efficient catalyst for the oxaziridinium-mediated epoxidation of olefins by Oxone®


07 Nov 2020

Synthesis works, but yields can be difficult to achieve.

As th electronegativity of the R-groups on the catalyst increases, yields tended to drop below reported values. While annoying, the purity of the finale compound was excellent. 

On a more positive note, the route proposed in this publication can be easily...
