Determining the total structure of metal nanoparticles is vital to understand their properties. In this work, first all-alkynyl-protected Ag nanocluster, Ag74(C≡CPh)44, was synthesized and structurally characterized by single crystal diffraction. atoms are arranged in a Ag4@Ag22@Ag48 three shell all 44 phenylethynyl ligands coordinated with μ3 mode. spite being absent 31P NMR study reveals that bidentate phosphine reacts Ag(I) form dinuclear complex, from which then released ligands. This...
Substituted alkenes are pivotal structural motifs found in pharmaceuticals and agrochemicals. Although numerous methods have been developed to construct substituted alkenes, a generally efficient, mild, catalytic platform for the conversion of alkynes this highly functionalized scaffold via successive C-C bond forming steps remains high demand. Here we describe an intermolecular, regio- syn-stereoselective alkylarylation terminal with tertiary alkyl oxalates photoredox-Ni dual catalysis....

A new copper-catalyzed [3 + 2] cycloaddition/oxidation reaction of nitro-olefins with organic azides has been developed to afford 1,4(-NO2),5-trisubstituted 1,2,3-triazoles. This sequence a broad substrate scope and affords NO2-substituted 1,2,3-triazoles high regioselectivities in good excellent yields. The involved oxidative process overcomes the elimination HNO2 for general cycloaddition azides, which shows atom economy potential applications.
Abstract Alkenylpyridines are important pharmaceutical cores as well versatile building blocks in organic synthesis. Heck reaction represents one of the most powerful platform for construction aryl-substituted alkenes, nevertheless, examples type coupling alkenes with pyridines, particularly branched selectivity, remain elusive. Here we report a catalytic, branch-selective pyridylation via sulfinate assisted photoredox catalysis. This proceeds through sequential radical...
The only feasible access to non-face-centered cubic (FCC) copper was by physical vapor deposition under high vacuum. Now, non-FCC is observed in a series of alkynyl-protected Cu53 nanoclusters (NCs) obtained from solution-phase synthesis. Determined single-crystal X-ray crystallography, the structures (C≡CPhPh)9 (dppp)6 Cl3 (NO3 )9 and its two derivatives reveal an ABABC stacking sequence involving 41 Cu atoms. It can be regarded as mixed FCC HCP structure, which gives strong evidence that...
