Biomimetic Mn(III) porphyrin-catalyzed aromaticity-breaking epoxidation of electron-deficient naphthalene [PDF]

Nature Communications
Selective catalytic aromaticity-breaking epoxidation of arenes remains an ongoing research challenge, attributed to the stability of aromatic systems, the occurrence of over-oxidation, and the instability of epoxides.

Niobia as an efficient catalyst for the epoxidation of dicyclopentadiene

Catalysis Communications, 2023
We studied the epoxidation of dicyclopentadiene (DCPD) with hydrogen peroxide over different heterogeneous catalysts. Among them, niobium pentoxide (Nb2O5) catalysts showed promising catalytic activity, giving mono- and di-epoxy DCPD with low amounts of ...

An Electrocatalytic/Heterogeneous Catalytic Cascade for Selective Production of Propylene Oxide via Anodic H₂O₂ Generation. [PDF]

Angew Chem Int Ed Engl
This work demonstrates a cascade strategy for the selective synthesis of propylene oxide (PO) by coupling anodic H2O2 generation with TS‐1 catalyzed propylene epoxidation. By immobilizing TS‐1 on a gas diffusion layer, the system achieves high PO productivity with efficient H2O2 utilization, providing a safer and greener alternative to conventional PO ...
