Light-induced olefin metathesis
Beilstein Journal of Organic Chemistry, 2010 Light activation is a most desirable property for catalysis control. Among the many catalytic processes that may be activated by light, olefin metathesis stands out as both academically motivating and practically useful.

Bidirectional Disulfide Metathesis Enables Recycling of High-Performance Thermoset Networks. [PDF]
Adv Sci (Weinh)A cyclic aromatic disulfide comonomer enables dual‐mode recyclable pDCPD thermosets through bidirectional disulfide metathesis. The resulting networks combine enhanced mechanical performance with thermal reprocessability and chemical depolymerization into reusable oligomeric fragments, allowing regeneration of high‐performance thermosets with minimal ...

Organocatalyzed Fluoride Metathesis [PDF]
Organic Letters, 2020 A new organocatalyzed fluoride metathesis reaction between fluoroarenes and carbonyl derivatives is reported. The reaction exchanges fluoride (F–) and alternate nucleophiles (OAc–, CO2R–, SR–, Cl–, CN–, NCS–). The approach provides a conceptually novel route to manipulate the fluorine content of organic molecules.

Supported Catalysts Useful in Ring-Closing Metathesis, Cross Metathesis, and Ring-Opening Metathesis Polymerization [PDF]
Polymers, 2016 Ruthenium and molybdenum catalysts are widely used in synthesis of both small molecules and macromolecules. While major developments have led to new increasingly active catalysts that have high functional group compatibility and stereoselectivity, catalyst/product separation, catalyst recycling, and/or catalyst residue/product separation remain an ...
