Journal ArticleDOI
Palladium(II) containing γ-Keggin silicodecatungstate that efficiently catalyzes hydration of nitriles.
TL;DR: The kinetic, mechanistic, and density functional theory calculation studies show that the dipalladium site plays an important role in the present hydration, and the nucleophilic attack of a hydroxide or water to the nitrile carbon atom is included in the rate-determining step.
Journal ArticleDOI
Heterogeneously catalyzed aerobic oxidative biaryl coupling of 2-naphthols and substituted phenols in water.
TL;DR: The kinetic data and kinetic isotope effect show that the reoxidation of the reduced catalyst is the rate-limiting step for the coupling reaction, and the present oxidative biaryl coupling reaction proceeds via the homolytic coupling of two radical species and the Ru(OH)x/Al2O3 catalyst acts as an one-electron oxidant.
Journal ArticleDOI
Recent progress in the development of solid catalysts for biomass conversion into high value-added chemicals
TL;DR: Recent progress in chemocatalytic processes for the production of five industrially important products as bio-based plastic monomers and their intermediates is comprehensively summarized.
Journal ArticleDOI
Cyanosilylation of Carbonyl Compounds with Trimethylsilyl Cyanide Catalyzed by an Yttrium‐Pillared Silicotungstate Dimer
Yuji Kikukawa,Kosuke Suzuki,Midori Sugawa,Tomohisa Hirano,Keigo Kamata,Kazuya Yamaguchi,Noritaka Mizuno +6 more
TL;DR: It is expected that POMs with large negative charges can nucleophilically activate TMSCN, thus resulting in promotion of cyanosilylations, as observed for Lewis base catalyzed cyanOSilylations.
Journal ArticleDOI
Strategic Design and Refinement of Lewis Acid–Base Catalysis by Rare-Earth-Metal-Containing Polyoxometalates
TL;DR: Among the POM catalysts examined, the neodymium-containing POM showed remarkable catalytic performance for cyanosilylation of various kinds of structurally diverse ketones and aldehydes, giving the corresponding cyanohydrin trimethylsilyl ethers in high yields.
