Primary Applications of Ruthenium(III) Chloride Hydrate

Ruthenium(III) Chloride Hydrate serves as a versatile Ru precursor for generating highly active ruthenium catalysts in selective transformations and advanced synthesis.

1. Olefin Metathesis Catalyst Preparation
   Acts as the primary ruthenium source for synthesizing Grubbs-type catalysts (1st, 2nd generation) and Hoveyda-Grubbs catalysts, enabling efficient ring-closing, cross, and ring-opening metathesis in pharmaceutical and polymer chemistry.

2. Hydrogenation & Transfer Hydrogenation
   Used to prepare homogeneous or supported Ru catalysts for selective reduction of carbonyls, imines, and alkenes, offering excellent enantioselectivity in asymmetric hydrogenation processes.

3. C–H Activation & Functionalization
   Facilitates Ru-catalyzed direct C–H arylation, alkenylation, and annulation of arenes and heterocycles, providing atom-economical routes to complex molecules.

4. Oxidation & Dehydrogenation Reactions
   Serves as precursor for Ru catalysts in alcohol oxidation, alkane dehydrogenation, and oxidative coupling, delivering high selectivity under mild conditions.

5. Pharmaceutical & Fine Chemical Synthesis
   Employed in key steps of API manufacturing, including metathesis and hydrogenation, offering scalability and functional group compatibility in GMP environments.

6. Advanced Materials & Nanotechnology
   Enables preparation of Ru nanoparticles, thin films, or supported clusters for electrocatalysis, fuel cells, and functional materials research.
