Autor: Hannah K. Box, T. Keith Hollis, Henry U. Valle, Tyler O. Howell, Griffin A. Burk, William E. Kennon

Publikováno v: Tetrahedron. 73:2191-2195

The coupling of N-heterocyclic azoles (imidazoles, benzimidazoles, triazoles) to bromobenzenes (1,2-; 1,3-; or 1,4) in a step-wise, sequential manner was accomplished by manipulation of reaction time and stoichiometry, which provided straight-forward

A new CCC-NHC pincer ligand precursor architecture based on 1,3-bis(N-alkylbenzimidazole)benzene has been synthesized and metalated using Ag2O, forming a homobimetallic Ag complex with a metal to ligand ratio of 1:1. The Ag complex was treated with e

ChemInform Abstract: An Efficient Synthesis of Bis-1,3-(3′-aryl-N-heterocycl-1′-yl)arenes as CCC-NHC Pincer Ligand Precursors

Autor: T. Keith Hollis, Tyler O. Howell, Aron J. Huckaba

Publikováno v: ChemInform. 45

A report that demonstrated an efficient methodology for the arylation of imidazoles has been extended to bis(N-heterocyclic) compounds. Using bis(aryl) iodonium salts provides high-yielding access to CCC-NHC ligand precursors in a single step. Exampl
