Selective synthesis of N-aryl hydroxylamines by the hydrogenation of nitroaromatics using supported platinum catalysts
TL;DR: In this article, substituted nitroaromatics were successfully hydrogenated to N-aryl hydroxylamines in excellent yields (up to 99%) using supported platinum catalysts such as Pt/SiO2 under a hydrogen atmosphere (1 bar) at room temperature.
Journal ArticleDOI
Remarkable acceleration of cyanosilylation by the mesoporous Al-MCM-41 catalyst
TL;DR: The presence of the heterogeneous mesoporous Al-MCM-41 catalyst remarkably accelerated the cyanosilylation of various aldehydes and ketones with trialkylsilyl cyanide, giving the corresponding cyanohydrin silyl ethers in quantitative yields under mild reaction conditions.
Journal ArticleDOI
Al-MCM-41 catalyzed three-component Strecker-type synthesis of α-aminonitriles
TL;DR: The Al-MCM-41 catalyzed three-component Strecker-type reaction was applicable to a wide range of ketones, aldehydes, and amines as mentioned in this paper.
Journal ArticleDOI
Unsymmetrical and Symmetrical Dipalladium Complexes with Bridging Diphenylsilyl Ligands. Structures of (Me3P)Pd(μ-SiHPh2)2Pd(PMe3)2 and [(Me3P)Pd(μ-SiHPh2)]2 in the Solid State and in Solution
TL;DR: In this paper, two bridging diphenylsilyl ligands were used to construct nuclear palladium complexes with an agostic interaction between H of μ-SiHPh2 and Pd and the symmetrical structure of 1 in solution is similar to that found in the crystals and is maintained in the temperature range +25 to −90 °C.
Journal ArticleDOI
A Simple Zinc Catalyst for Carbamate Synthesis Directly from CO2
TL;DR: Several zinc salts were employed as catalysts for the synthesis of carbamates directly from aromatic amines, CO2 , and silicate esters, and Zn(OAc)2 offered the best performance, which can be explained by carboxylate-assisted proton activation.
