Highly effective and selective Pd-catalyzed coupling reactions of 1,1-dibromo-1-alkenes with various arylboronic acids have been performed in aqueous solution under mild conditions. The method is simple, economic, and practical for the synthesis of triarylethene-based compounds. Copyright

Imidazolium salts bearing triazole groups are synthesized via a copper catalyzed click reaction, and the silver, palladium, and platinum complexes of their N-heterocyclic carbenes are studied. [Ag4(L1) 4](PF6)4, [Pd(L1)Cl](PF6), [Pt(L1)Cl](PF6) (L1=3-((1-benzyl-1H-1,2,3-triazol-4-yl)methyl)-1- (pyrimidin-2-yl)-1H-imidazolylidene), [Pd2(L2)2Cl 2](PF6)2, and [Pd(L2)2](PF 6)2 (L2=1-butyl-3-((1-(pyridin-2-yl)-1H-1,2,3-triazol-4- yl)methyl) imidazolylidene) have been synthesized and fully characterized by NMR, elemental analysis, and X-ray crystallography. The silver complex [Ag 4(L1)4](PF6)4 consists of a Ag 4 zigzag chain. The complexes [Pd(L1)Cl](PF6) and [Pt(L1)Cl](PF6), containing a nonsymmetrical NCN' pincer ligand, are square planar with a chloride trans to the carbene donor. [Pd 2(L2)2Cl2](PF6)2 consists of two palladium centers with CN2Cl coordination mode, whereas the palladium in [Pd(L2)2](PF6)2 is surrounded by two carbene and two triazole groups with two uncoordinated pyridines. The palladium compounds are highly active for Suzuki-Miyaura cross coupling reactions of aryl bromides and 1,1-dibromo-1-alkenes in neat water under an air atmosphere.
