Synthesis and characterization and application of zirconate(IV) complexfor C–C coupling reactions

Carbon-Carbon bond forming reactions are among the important catalytic transformations inorganic synthesis[۱,۲]. Heterogeneous catalysts have been highly investigated in the C-C crosscoupling reactions [۳]. The metal compelexs show high catalytic activities in various crosscouplingreactions of an aryl or alkenyl halide[۴]. Highly efficient catalysts based on zirconiumnanoparticles in C-C cross-coupling reaction were reported[۵].In this work, synthesis and characterization of the Zr(IV) complex, [Ph۳PCH۲C۶H۴CH۲PPh۳]۲[ZrCl۶], has been reported. The prepared compound was characterized using elemental analysisand spectroscopic methods IR, ۱H, and ۱۳C NMR. Finally, this compound was investigated as aneffective catalyst in Suzuki and Heck carbon-carbon coupling reactions. All products wereprepared in the presence of this complex in high efficiency. The obtained compound can berecovered and it can be reused without significant reduction in its catalytic activity
