| Abstract: | A new polymer-anchored Pd(II) complex has been synthesized, characterized and its catalytic activity was investigated for the Suzuki cross-coupling reaction between aryl halides and arylboronic acid in the presence of K2CO3 as a base, for Heck olefination of aryl halides with alkenes, and for cyanation reaction of aryl iodides with K4Fe(CN)6 in presence of Et3N as base. The key features of the catalyst include rapid reactions with excellent conversion without the use of phosphine ligands and total stability under the reactions conditions. The catalyst was recovered by simple filtration and reused five-times without significant loss of catalytic activity. |
