Two bis-imidazolium salts LH2·Cl2 and LH2·(PF6)2 with acylated piperazine linker and two N-heterocyclic carbene (NHC) silver(I) and palladium(II) complexes [L2Ag2](PF6)2 (1) and [L2Pd2Cl4] (2) were prepared. The crystal structures of LH2·Cl2 and 1 were confirmed by X-ray analysis. In 1, one 26-membered macrometallocycle was generated through two silver(I) ions and two bidentate ligands L. The catalytic activity of 2 was investigated in Sonogashira, Heck-Mizoroki and Suzuki-Miyaura reactions. The results displayed that these C—C coupling reactions can be smoothly carried out under the catalysis of 2.

Boron-doping has long been recognized as a promising LUMO energy-lowering modification of graphene and related polycyclic aromatic hydrocarbons (PAHs). Unfortunately, synthetic difficulties have been a significant bottleneck for the understanding, optimiz

A new functionalized N-heterocyclic carbene PdII complex, [1,1′-(hexylene-1,6-diyl)bis(3-n-butylbenzimidazol-2-ylidene)][PdCl 2(CH3CN)]2 (2) has been synthesized by reaction of NHC-Ag transmetalation reagent with PdCl2(CH3CN) 2. The molecular structure of 2 adopts an open conformation. Complex 2 was tested as a catalyst for Suzuki-Miyaura couplings of aryl halides with arylboronic acids in water and air. The results of these efforts show that 2 is an efficient precatalyst for such reactions. In addition, 2 is a good catalyst in Heck-Mizoroki reactions of aryl bromides with styrene. A new 1,6-hexylene-bridged bis-N-heterocyclic carbene PdII complex was prepared and characterized. The catalytic activities of this complex in Suzuki-Miyaura and Heck-Mizoroki reactions were investigated. Copyright
