A procedure for the synthesis of fluorinated imidazole derivatives from propargyl amidines has been developed. Under gold(I) catalysis, propargyl amidines were converted into 5-fluoromethyl imidazoles in the presence of ...
Two functional main-chain linear polyrotaxanes, one a covalent polymeric chain that threads through many macrocycles (P1) and the other a poly[n]rotaxane chain that is composed of many repeating rotaxane units (P2), were...
The interactions of three cationic distyryl dyes, namely 2,4-bis(4-dimethylaminostyryl)-1-methylpyridinium (1?a), its derivative with a quaternary aminoalkyl chain (1?b), and the symmetric 2,6-bis(4-dimethylaminostyryl)-...
Heteronuclear AuPd nanoparticles were prepared and immobilized in the functionalized ionic liquid [C2OHmim][NTf2]. The structural and electronic properties of the nanoparticles were characterized by a range of techniques...
The preparation of dinuclear rhodium clusters and their use as catalysts is challenging because these clusters are unstable, evolving readily into species with higher nuclearities. We now present a novel synthetic route ...
A unique heterobimetallic disulfur monoradical, complex 2, with a diamond-shaped {NiS2Pt} core has been synthesized by two-electron reduction of a supersulfido-(nacnac)nickel(II) complex (nacnac=&beta-diketiminato) with ...
This paper reports a theoretical analysis of the electronic structure and magnetic properties of a tetranuclear CuII complex, [Cu4(HL)4], which has a 4+2 cubane-like structure (H3L=N,N'-(2-hydroxypropane-1,3-diyl)bis(ace...
A classical conundrum in origin-of-life studies relates to the nature of the first chemical system: was it a carrier of genetic information or a facilitator of cellular compartmentalization? Here we present a system comp...
A new series of C-6 unsubstituted tetrahydropyrimidines 6 have been directly synthesized via a convenient urea-catalyzed chemoselective five-component reaction (5CR) under mild conditions. Compounds 6 show typical aggreg...
The enhanced antioxidant activity of surface-functionalized gold nanoparticles (AuNPs) synthesized by self-assembly has attracted great attention, but little is known about the mechanism behind the enhanced activity. To ...
