During the past two decades a variety of transition-metal catalyzed reactions have been introducedin synthetic organic chemistry. Among the most popular examples are asymmetric oxidations and reductionsand a variety of cross-coupling reactions to form C − C and C-heteroatom bonds. Examples are the Heck reaction, Suzuki–Kumadaand Sonagashira coupling reactions and the aryl-aminations introduced by...
Two examples of the application of ruthenium catalysts in fine chemical synthesis are given in this paper. In the first part, protocols for both asymmetric and non-asymmetric epoxidation reactions of olefins employing hydrogen peroxide as a “green” re-oxidant are described. Ruthenium pyridine-2,6-dicarboxylate complexes containing tridentate N-donor ligands are used as homogeneous catalysts. In the...
