Syntheses and activities of indol-2-ylidene-ligated ruthenium-based olefin metathesis catalysts [PDF]

, 2022
Here we report a new family of indol-2-ylidene (IdY)-ligated Ru-based olefin metathesis catalysts (Ru−IdY) and their X-ray crystal structures which show a unique conformation of the ruthenium environment.

Catalytic olefin metathesis in blood. [PDF]

Chem Sci, 2023
A Ru-based artificial metalloenzyme (ArM) at just 1–5 mol% could catalyze olefin metathesis in blood to construct various molecular scaffolds. The cancer-targeting ArM at a low dosage could elicit tumor growth inhibition by in vivo drug synthesis.

Heterogeneous catalysts for olefin metathesis

Catalysis Communications, 2023
Over the past 30 years, many strategies have been developed to immobilize well-defined metathesis catalysts on solid supports. The use of heterogeneous catalysis resulted in increased purity of the product and the possibility of recycling the catalyst ...
