A highly efficient noble-metal-free homogeneous system for a cross-coupling hydrogen evolution (CCHE) reaction is developed. With cheap, earth-abundant eosin Y and molecular catalyst Co(dmgH)2Cl2, good to excellent yields for coupling reactions with a variety of isoquinolines and indole substrates and H2 have been achieved without any sacrificial oxidants. Mechanistic insights provide rich information on the effective, clean, and economic CCHE reaction.
发展了一种高效、无贵金属的均相体系用于交叉偶联氢析出反应（CCHE）。使用廉价、丰富的曙红 Y 和分子催化剂 Co(dmgH)2Cl2，在没有任何牺牲氧化剂的情况下，实现了与多种异喹啉和吲哚底物及 H2 的偶联反应的良好至优秀收率。机理研究为高效、清洁、经济的 CCHE 反应提供了丰富的信息。
