  Ligand-promoted reaction on silver nanoparticles: phosphine-promoted, silver nanoparticle-catalyzed cyclization of 2-(1-hydroxy-3-arylprop-2-ynyl)phenols

  摘要：

  A highly efficient annulation of 2-(1-hydroxy-3-arylprop-2-ynyl)phenols leading to the key intermediates to synthesize aurones was catalyzed by silver nanoparticles/carbon black-supported silver nanoparticles. In the presence of phosphine ligand, both the catalysts show excellent catalytic activities in the reaction and give the products with good yields as well as excellent regio- and stereo-selectivities in a water-toluene mixed solvent. Furthermore, the catalysts can be recovered and recycled effectively several times. (C) 2010 Elsevier Ltd. All rights reserved.

  Water-Promoted, Silver–Phosphine Complex–Catalyzed Stereoselective Cyclization of 2-(1-Hydroxy-3-arylprop-2-ynyl)phenols Leading to a Highly Efficient Approach to Aurones

  摘要：

  Silver-phosphine complexes can be utilized as highly efficient catalysts for the cyclization of 2-(1-hydroxy-3-arylprop-2-ynyl)phenols (1) to give product 2, key intermediates to synthesize aurones (4), with good yields and stereoselectivities in water-toluene mixed solvent. With fluoride as the counteranion, complete E- or Z-stereoselectivities were achieved at high temperature or room temperature, respectively. Furthermore, after removing water from the reaction mixtures, the toluene solution containing crude products 2 can be treated by MnO2 directly without further purification, to give aurones 4 in good yields.

  Aurones were synthesized through an oxidation-cyclization tandem reaction of 2-(1- hydroxyprop-2-ynyl)phenols catalyzed by copper nanoparticles (Cu NPs) with bipyridine as the ligand. In the reaction, oxygen worked as a green and mild oxidant to give the best results. Cu NPs were dually activated by bipyridine ligand and water, and showed highly efficient catalytic activities to the oxygen oxidation
