Abstract
![]()
Interest in the catalytic
activation of peroxides, together with
the requirement of stereoselectivity for the production of enantiopure
sulfoxides, has made sulfoxidation the ideal playground for theoretical
and experimental physical organic chemists investigating oxidation
reactivity. Efforts have been dedicated for elucidating the catalytic
pathway regarding these species and for dissecting out the dominant
factors influencing the yield and stereochemistry. In this article,
Ti(IV) and Hf(IV) aminotriphenolate complexes have been prepared and
investigated as catalysts in the presence of peroxides in sulfide
oxidation. Experimental results have been combined with theoretical
calculations obtaining detailed mechanistic information on oxygen
transfer processes. The study revealed that steric issues are mainly
responsible for the formation of intermediates in the oxidation pathway.
In particular, we could highlight the occurrence of a blended situation
where the steric effects of sulfides, ligands, and oxidants influence
the formation of different intermediates and reaction pathways. Steric issues are mainly responsible

Abstract
Performing a heterogeneous catalysis with proteins is still a challenge. Herein, we demonstrate the importance of cross-linked crystals for sulfoxide oxidation by an artificial enzyme. The biohybrid consists of the insertion of an iron complex into a NikA protein crystal. The heterogeneous catalysts displays a better efficiency-with higher reaction kinetics, a better stability and expand the substrate scope compared to its solution counterpart. Designing crystalline artificial enzymes represents a good alternative to soluble or supported enzymes for the future of synthetic biology.
