Abstract
A facile and readily available Fe-ppm-Pd/C catalyst has been developed for catalyzing Suzuki-Miyaura cross-coupling reactions. When combined with dicyclohexyl(2′,6′-dimethoxy-[1,1′-biphenyl]-2-yl) phosphine (SPhos), this catalyst, with low levels of palladium (as low as 180 ppm), efficiently facilitates cross-coupling reactions between aryl boronic acids (or aryl neopentyl-1,3-diol boronic ester) and a wide range of aryl halides, including inactivated aryl chlorides. Additionally, the recovered Fe-ppm-Pd/C catalyst has demonstrated sustained catalytic activity over four runs, indicating minimal decline in performance. This suggests the catalyst's potential for long-term use and its practicality in industrial applications.
