Book excerpt: Homogeneous Hydrogenation and Metathesis Reactions, a volume in the Advances in Catalysis series, covers hydrogenation and metathesis reactions in two separate sections. The first section is devoted to homogeneous hydrogenation reactions and related processes, including hydrogenation of alkenes, esters, olefins, etc. In the second section, the metathesis reactions of olefins, alkenes, and alkynes are presented. In addition, the industrial application of homogeneous metathesis reactions is investigated. Includes thermodynamic and kinetic studies of homogeneous catalysts Describes transition metal, ligand, and solvent role in homogeneous catalysts Explains preparation, characterization, deactivation, and regeneration of homogeneous catalysts Presents homogeneous catalysts by clusters, carbenes, fixed metal-complexes, and liquid-liquid multiphase catalysts
