Numerous industrial processes utilise gaseous chemical feedstocks to produce useful chemical products. Atmospheric and other small molecule gases, including anthropogenic waste products (e.g. carbon dioxide), can be viewed as sustainable building blocks to access value-added chemical commodities and materials. While transition metal complexes have been well documented in the reduction and transformation of these substrates, molecular complexes of the terrestrially abundant alkaline earth metals have also demonstrated promise with remarkable reactivity reported towards an array of industrially relevant gases over the past two decades. This review covers low oxidation state and hydrido group 2 complexes and their role in the reduction and transformation of a selection of important gaseous substrates towards value-added chemical products.

低氧化态氢基2配合物：合成及其在气态底物活化中的应用

许多工业过程利用气态化学原料来生产有用的化学产品。大气和其他小分子气体，包括人为废物（例如二氧化碳），可以被视为获取增值化学商品和材料的可持续基石。虽然过渡金属配合物在这些底物的还原和转化过程中已得到充分证明，但陆地上丰富的碱土金属的分子配合物也显示出了在过去二十年中对一系列工业相关气体具有显着反应性的前景。本综述涵盖了低氧化态和氢基 2 配合物及其在将一系列重要气态底物还原和转化为增值化学产品中的作用。
