Ruthenium-Catalyzed Reactions for Organic Synthesis.

Catalysis by heteropoly acids (HPAs) and related compounds is a field of growing importance, attracting increasing attention worldwide, in which many new and exciting developments are taking place in both research and technology [1–111, HPAs are polyoxometalates incorporating anions (heteropolyanions) having metal-oxygen octahedra as the basic structural units [ll-141. Among a wide variety of HPAs those belonging to the so-called Keggin series are the most importance for catalysis. They include heteropolyanions (HPANs)

Heteropoly Acids and Related Compounds as Catalysts for Fine Chemical Synthesis

Monomeric and extended oxo-centered triruthenium clusters

Oxidation of 2,3,6-Trimethylphenol over Ti- and V-Containing Mesoporous Mesophase Catalysts: Structure–Activity/Selectivity Correlation

The use of heteropolycompounds (heteropolyacids and their salts) as acid and oxidation catalysts of fine organic synthesis reactions is examined. The use of the heteropolycompounds in the synthesis of antioxidants, medicinal preparations, vitamins and other products produced on a small scale is discussed. Examples of the practical application of catalysis by heteropolycompounds are presented. The bibliography includes 177 references.
