从工业角度来看，有机氯化物由于其丰富和低成本，是铃木-宫浦交叉偶联反应中最理想的底物。然而，钯纳米粒子在芳酰氯铃木偶联中的催化应用仍然是一个挑战。在这里，我们设计了一种新的催化剂，将Pd NPs与Co3[Co(CN)6]2纳米晶体结合，用于芳基氯化物的Suzuki-Miyaura偶联。该纳米催化剂在铃木反应中表现出良好的活性（80°C时产率为86.2%）、高TOF、稳定性好、易于分离、良好的可重复使用性（5个循环后初始速率不降低）和低成本。
Because of their abundance and low cost, organo chlorides are the most desirable substrates from the industrial point of view in Suzuki-Miyaura cross-coupling reactions. However, catalytic application of Pd nanoparticles (NPs) for Suzuki coupling of aryl chlorides is still a challenge. Here, we design a novel catalyst by combining Pd NPs with Co3[Co(CN)6]2 nanocrystals for Suzuki-Miyaura coupling of aryl chlorides. This nanocatalyst demonstrated good activity (yield 86.2% at 80 °C), high TOF, great stability, easy separation, excellent reusability (initial rates were not reduced after five cycles) and low cost in Suzuki reactions.
