一种特别优化的空气稳定的Pd/活性炭催化剂被证明是一种高活性（TON高达36，000），选择性和方便的非均相催化剂，用于Heck，Suzuki和Sonogashira反应中芳基卤化物的CC偶联。所开发的Pd/ C催化剂允许极低的Pd浓度（对于Heck偶联低至0.0025摩尔%，对于Suzuki偶联低至0.005摩尔%）和芳基溴在几小时内的高转化率。钯的分离和回收容易且完全。
A specially optimized air-stable Pd on activated carbon catalyst is demonstrated to be a highly active (TON up to 36,000), selective and convenient heterogeneous catalyst for CC couplings of aryl halides in Heck, Suzuki, and Sonogashira reactions. The Pd/ C catalyst developed allows extremely low Pd concentrations (down to 0.0025 mol% for Heck coupling, 0.005 mol% for Suzuki coupling) and high conversions of aryl bromides within a few hours. Easy and complete Pd separation and recovery is possible.
