Catalytic reduction reactions play a major role in modern chemistry and are often based on hydrogen gas as a reducing agent. However, the high reactivity of hydrogen is often accompanied by low selectivity on the simple catalysts. Herein, we showed that the usage of syngas as a reducing agent can be a more efficient and selective strategy. Based on control experiments, a plausible mechanism was proposed
催化还原反应在现代化学中发挥着重要作用,通常以氢气为还原剂。然而,氢气的高反应性往往伴随着对简单催化剂的低选择性。在这里,我们表明使用合成气作为还原剂可能是一种更有效和选择性的策略。基于对照实验,提出了一种合理的机制来解释合成气的优越性能。这种方法的多功能性通过成功应用于使用不同金属催化剂的三种反应来证明:直接还原胺化、还原酯化和串联 CH-还原烷基化-水解-脱羧。催化剂周转量达到 30,000。而且,
