Synthesis of Zr-metal organic frameworks modified for the Suzuki andHeck reactions as an effective and heterogeneous catalyst

Metal organic frameworks (MOFs) demonstrate an important class of crystalline porouscompounds produced from organic ligands (linkers) and metal ions or clusters [۱].Functionalization of MOFs is crucial in searching their structural and chemical variety foraboundanc potential applications [۲]. MOFs were commonly suitable for various reactionsubstrates with different substituents in both Suzuki and Heck reactions [۳]. Herein, heterogeneousZr- MOF (UiO-۶۷) catalyst was synthesized to perform the Suzuki–Miyaura and Heck crosscouplingreactions. Nowadays, heterogeneous catalytic systems have attracted significant attentiondue to their facility of dissociation from liquid phase reaction matrices. Moreover, MOFs are alsooften utilized as the host of the catalytically active constituent [۴]. The immobilized catalyst wasrecyclable for at least up to ۵ cycles without reduction in the efficiency of the coupled product.Modified Zr- MOF (UiO-۶۷) was synthesis on the basis of a mixture of ۴,۴ -biphenyldicarboxylicacid (H۲BPDC) ligand and ZrCl۴ by solvothermal method
