We report here the synthesis and characterization of a new calix[8]arene-supported PEPPSI-IPr Pd polymetallic complex. This complex, showing greater steric hindrance around the Pd centers compared with previous calix[8]arene-based catalysts, demonstrated high reactivity and selectivity for the Suzuki–Miyaura coupling of aryl chlorides under mild conditions. Along with this good performance, the new catalyst showed low Pd leaching into the final Suzuki–Miyaura coupling products, indicative of a heterogeneous-type reactivity. This rare combination of good reactivity towards challenging substrates and low metal leaching offers great promise at both academic and industrial levels. View Full-Text
