“…5. With the former, Wacker-type oxidation of the olefinic double bond was primarily observed while the latter underwent highly selective (>99%) oxidation of the alcohol moiety [32]. The latter result is consistent with the pioneering work of Moiseev and coworkers [33] who showed that giant Pd clusters (nowadays known as Pd nanoparticles) catalyze the oxidation of alcohol moieties and selectively oxidize allylic C H bonds in olefins.…”

“…This suggested that we were concerned with totally different types of catalyst. Indeed, further investigation revealed that the Pd(II) neocuproin complex dissociates completely to afford Pd nanoclusters which are the actual catalyst [85]. Moiseev and coworkers [68,86] had previously shown that giant Pd clusters (nowadays known as Pd nanoclusters) are good catalysts for the oxidation of alcohol moieties and selectively oxidize allylic CÀH bonds in alkenes.…”

“…Pt nanoparticles supported on a water-soluble anion exchange resin exhibit excellent E-factors (12.8 kilo waste per kilo product) in addition to very good activity and selectivity for alcohol oxidation [136]. Similarly, water has been used as solvent for, for example, benzylic and primary alcohol oxidations over supported or stabilized Pd [137], Pt [138], and Au [139] clusters.…”

IntroductionCatalytic selective oxidation (selox) is an important class of clean chemical transformations employed in the synthesis of valuable chemical intermediates, and a test bed for many fundamental concepts within heterogeneous catalysis and surface science. The selox of alcohols, carbohydrates, and aromatics is especially challenging in terms of understanding the dynamics of chemical reactions at the liquid-solid-gas interface, and requires new spectroscopic tools and analytical protocols to provide quantitative spatiotemporal information on structure-function relationships in order to optimize reaction conditions and design next-generation selox catalysts. Advances in inorganic methodologies to synthesize tunable nanostructures, and synchrotron science and the parallel development of multidimensional spectroscopies, afford new possibilities for understanding the operation of catalysts under working conditions (operando), and thereby nanoengineering the active site for improved activity, selective, and lifetime in selox chemistry. Applications of Selective OxidationThe oxidative dehydrogenation of alcohols represents key steps in the synthesis of aldehyde, ketone, ester, and acid intermediates employed within the fine chemical, pharmaceutical, and agrochemical sectors, with allylic aldehydes in particular high-value components used in the perfume and flavoring industries [1]. For example, crotonaldehyde is an important agrochemical and a valuable precursor for the food preservative sorbic acid, while citronellyl acetate and cinnamaldehyde confer rose/fruity and cinnamon flavors and aromas, respectively. There is also considerable interest in the exploitation of biomass-derived feedstocks such as glycerol (a by-product of biodiesel synthesis from plant or Heterogeneous Catalysts for Clean Technology: Spectroscopy, Design, and Monitoring, First Edition.
