CO is a greenhouse gas and a nontoxic, easily available and renewable C feedstock. H is a clean and cheap reductant that can be obtained from renewable energy. Olefins are platform chemicals that can be produced from a variety of raw materials such as petroleum, coal and renewable biomass. The production of carboxylic acids by combining olefins, CO and H is a sustainable and very promising protocol. However, only a few advances in this topic have been achieved because novel catalysts need to be developed. In this work, we demonstrate that a simple iridium-based catalyst could efficiently promote the synthesis of C carboxylic acids via the reaction of olefins with CO and H. The reaction was effectively accelerated by a simple iridium-based catalytic system at 170 °C, which may be applied to various olefin substrates. The catalytic mechanism was studied through a series of control experiments. The findings contribute to advancing the sustainable production of valuable products by the reaction of renewable CO and green H with platform chemicals.
一氧化碳是一种温室气体，也是一种无毒、易于获取且可再生的碳原料。氢气是一种可从可再生能源中获得的清洁且廉价的还原剂。烯烃是可由石油、煤炭和可再生生物质等多种原料生产的平台化学品。通过将烯烃、一氧化碳和氢气相结合来生产羧酸是一种可持续且非常有前景的方法。然而，由于需要开发新型催化剂，在这个课题上仅取得了一些进展。在这项工作中，我们证明了一种简单的铱基催化剂能够通过烯烃与一氧化碳和氢气的反应有效地促进碳羧酸的合成。在170℃下，一个简单的铱基催化体系有效地加速了该反应，该体系可能适用于各种烯烃底物。通过一系列对照实验研究了催化机理。这些发现有助于推动通过可再生的一氧化碳和绿色氢气与平台化学品的反应来可持续生产有价值的产品。
