Asymmetric Metal-Templated Synthesis of Congested Proline Derivatives via [3 + 2] Cycloaddition Reaction

Abstract An asymmetric synthesis of congested proline derivatives with three defined carbon stereocenters (including two quaternary ones) through an Ag(I)-catalyzed [3 + 2] cycloaddition reaction is described. The atom-economic coupling of a chiral dehydroalanine Ni(II) complex w...

2,3-Diphenyldibenzo[b,f]imidazo[1,2-d][1,4]oxazepine-6,7-dicarbonitrile

The study focuses on the synthesis and structural characterization of 2,3-diphenyldibenzo[b,f]imidazo[1,2-d][1,4]oxazepine-6,7-dicarbonitrile. The target compound was obtained via a nucleophilic aromatic substitution reaction between 2-(2-hydroxyphenyl)-4,5-diphenyl-1H-imidazole...

Synergy of Phenylsilsesquioxane and Pyridylpyrazolate Ligands in Hexacopper Cages: Approach to Catalytic Toluene Oxidation

Abstract Cage-like Cu6M2 (M = Li or Na) complexes, containing two pairs of ligands, Si5-cyclic silsesquioxanes and pyrazolylpyridines, have been obtained. Two central (Cu···Cu···Cu···M) tetramers are sandwiched by Si ligands, while pyrazolylpyridines behave simultaneously in chel...

Fluorite‐Type Silsesquioxane‐Protected Cerium Cluster as Molecular Analog of Highly Reduced Nanoceria Fragment for Efficient Photocatalysis

ABSTRACT The surface oxygen vacancy defects generated from the abstraction of lattice oxygen atoms of bulk ceria accompanied by the reduction of Ce IV to Ce III , are considered to play a pivotal role in photocatalysis. As ideal molecular models of nanoceria, atom‐precise cerium‐...
