• Palladium supported SBA-functionalizd 1,2-dicarboxylic acid: The first Pd-based heterogeneous synthesis of fluorenones
  作者：Abolfazl Mohammadkhanni、Ayoob Bazgir

  DOI：10.1016/j.mcat.2017.12.035

  日期：2018.3

  The first Pd-based heterogeneous homo- and cross-coupling reactions for the fluorenones synthesis are reported. The palladium supported SBA-functionalizd 1,2-dicarboxylic acid (Pd@DCA-SBA) was prepared and characterized by the FT-IR, TGA, AAS, TEM, and EDS measurements. The prepared catalyst exhibited a high performance in some homo and cross coupling reactions for the synthesis of fluorenone derivatives using 2-bromo or 2,7-dibromo fluorenone in ethanol-water as green solvent medium.
