• Palladium/2,2′-bipyridyl/Ag2CO3 catalyst for C–H bond arylation of heteroarenes with haloarenes

  日期：2011.6

  Pd/bipy-based catalytic system for the C–H bond arylation of heteroarenes with haloarenes is described. The complex PdBr2(bipy)·DMSO, whose structure was unambiguously determined by X-ray crystallography, turned out to be a general catalyst precursor for the process. The reaction is applicable to a range of electron-rich five-membered heteroarenes, such as thiophenes, thiazoles, benzofurans, and indoles

  Pd(II)-MoS2 catalyst was designed by affording Pd2+ salt on the surface of single-layered molybdenum disulfide nanosheets.. Based on the dispersible template, this metal salt and molybdenum disulfide complex offered several advantages, including easy preparation, low cost, and capability to prepare excellent dispersible metal ion cluster nanostructures. The application of this complex in alkenylation of heteroaromatics was reported. Direct C-H activation of indoles, furans and thiophenes was carried out to combine with several kinds of terminal olefins. This catalyst also performed high efficiency in several other kinds of coupling reactions. Thus, a universal suitable catalyst for C-H activation and CC bond formation was invented by a convenient in situ preparation. (C) 2015 Elsevier B.V. All rights reserved.
