A bifunctional cobalt pyridonate complex effectively catalyzes the hydroboration of CO to the boryl formate at very mild conditions (0.1-1 mol% cat., 1 bar CO, r.t., 5 min, 100% yield, TON 1000, TOF 12 000 h). At higher temperature, clean conversion to the methoxyborane was achieved (98% yield). Mechanistic studies indicate formation of a ligand-derived cobalt hydride species.
一种双功能吡啶酸钴配合物在非常温和的条件下（0.1 - 1 mol%催化剂，1 bar CO，室温，5分钟，产率100%，TON 1000，TOF 12000 h⁻¹）能有效催化CO硼氢化生成甲酸硼酸酯。在较高温度下，可实现向甲氧基硼烷的完全转化（产率98%）。机理研究表明形成了一种源自配体的钴氢化物物种。
