Abstract
|
the pd supported amidoxime(Ao)-functionalized Fe3O4(Fe3O4/AO/Pd) hybride material was used as an effective and recyclable nanocatalyst in Suzuki-Miyaaura coupling reactions. The catalyst was very effective for the Suzuki-Miyaaurra reaction of aryl halides (Ar-I, Ar-Br, Ar-Cl) with phenyl boronic acid and conversion was execellent in most cases. The yields of the products were in the range from 7-98. The catalyst showed good stability and could be recovered and reused for six reaction cycles without a significant loss in its catalytic activity, Also, awide range of N-arylated indoles are selectively synthesized throgh intera molecular C (aryl)-N bond formation from the corresponding aryl iodides and indoles through Ulmann-type coupling reactions in the presence of the prepared catalyst.
