White‐Light‐Mediated Imidazole Catalysis Toward Terpene‐Based Thermosets

open access: yesAngewandte Chemie, Volume 138, Issue 39, 21 September 2026.
White‐light irradiation enables the photoinitiator‐free curing of fully bio‐based terpene epoxy–anhydride systems. A light‐induced switch in epoxide ring‐opening selectivity leads to colorless, transparent thermosets with enhanced thermomechanical performance, revealing an unexpected pathway for sustainable terpene‐based network formation.

Heterogenisation of ketone catalysts within mesoporous supports for asymmetric epoxidation

open access: yes, 2013
The synthesis of the first mesoporous silica (150 Å) anchored carbohydrate-derived chiral ketone is described. This new heterogeneous catalyst has been shown to be effective in the asymmetric epoxidation of olefins by oxone.
