Rapid progress in chemistry and nanotechnology made nanoparticle (NP) catalysisa key focus of research and industry. Organic synthesis involving nanoparticles isalready well established in many laboratories. Nanoparticles used in the synthesis ofdrugs, dyes, molecular electronics, etc., are available in a variety of morphologies andtypes. These can be either zero oxidation-state metal nanoparticles or nanosalts witha positively charged metal bound to heteroatoms [1, 2]. A given type of nanoparticlesmay exhibit high catalytic activity in a particular family of organic reactions andbe inactive in another type of reactions [3, 4]. Investigation of catalytic activity ofsuch nanoparticles and mechanisms of their action are a priority for both organicchemistry and catalytic science [5].The requirements of green chemistry and improved economic efficiency, as wellas the needs of basic research, support the studies of nanoscale catalytic systems.However, studying the behavior of nanoparticles in solution is complicated forseveral reasons. Just one type of catalyst precursor introduced into a reactionsystem may produce a variety of particles in solution, i.e. the chemical nature ofthe introduced catalyst may change under the influence of the reaction medium.Nanoparticles introduced to a solution may be transformed into soluble metal salts,while introduction of metal salts may cause formation of nanoparticles during thereaction.Classifying the variety of newly formed particles into catalytically active and “deadweight” species is a nontrivial task that requires comprehensive investigations. Thischapter provides a brief introduction into dynamic systems (including cocktail-typesystems) with a survey of methods suitable for studying the reaction mechanisms.
