The Name is 4,4′-Dibromobiphenyl. Through research, I have a further understanding and discovery of 92-86-4. Quality Control of 4,4′-Dibromobiphenyl
Main observation and conclusion Two bis-imidazolium salts LH2 center dot Cl-2 and LH2 center dot(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 center dot Cl-2 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.
