A new functionalized N-heterocycliccarbene PdII complex, [1,1′-(hexylene-1,6-diyl)bis(3-n-butylbenzimidazol-2-ylidene)][PdCl2(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–Miyauracouplings of aryl halides with arylboronic acids in water and

salts LH2·Cl2 and LH2·(PF6)2 with acylated piperazine linker and two N‐heterocycliccarbene (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

Boron-doping has long been recognized as a promising LUMO energy-lowering modification of graphene and related polycyclicaromatichydrocarbons (PAHs). Unfortunately, synthetic difficulties have been a significant bottleneck for the understanding, optimization, and application of precisely boron-doped PAHs for optoelectronic purposes. Herein, a facile one-pot hydroboration electrophilic borylation
