Immobilization of Olefin Metathesis Catalysts on Monolithic Sol-Gel: Practical, Efficient, and Easily Recyclable Catalysts for Organic and Combinatorial Synthesis.

Glass-bound Ru-based catalysts! Ru-containing glass pellets efficiently promote olefin metathesis reactions and are easily employed in syntheses of compound libraries. These robust catalysts are active in air and commercially available solvents, can be recycled up to 16 times, and removed from reaction mixtures with a simple pair of tweezers (minimal solvent waste).
