ScholarBank@NUS Repository. https://doi.org/10.1021/om700949s||Abstract:||A new benzenimidazole-functionalized imidazolium-based N-heterocyclic carbene complex of Pd(II) has been prepared from facile transmetalation via a Ag(I) precursor. The latter was obtained from a condensation reaction between Ag2O and benzenimidazolium salt. Single-crystal X-ray crystallography revealed an unusual trinuclear AgSCl2(M-Cl2(μ-N-C) 2 (N-C = 3-methyl-1-(l-ethyl-2-methylbenzoyl)imidazolin-2-ylidene) intermediate in which the central carbene-supported Ag(I) is flanked by two imidazolecoordinated Ag(I). The hybrid ligand (N-C), carrying two heterodonors of benzenimidazole and carbene, is bridging in Ag(I) but chelating in Pd(II), The latter mononuclear PdCl2(η-N-C) is active toward Suzuki-Miyaura coupling of aryl bromides and boronic acids, giving a TON up to 11 750 within 4 h at rt. © 2008 American Chemical Society.||Source Title:||Organometallics||URI:||http://scholarbank.nus.edu.sg/handle/10635/93164||ISSN:||02767333||DOI:||10.1021/om700949s|
