Nanolayered cobalt–molybdenum sulphide (Co–Mo–S) materials have been established as excellent catalysts for C–S bond construction. These catalysts allow for the preparation of a broad range of thioethers in good to excellent yields from structurally diverse thiols and readily available primary as well as secondary alcohols. Chemoselectivity in the presence of sensitive groups such as double bonds,
纳米层硫化钴钼(Co-Mo-S)材料已被确定为 C-S 键构建的优异催化剂。这些催化剂可以用结构多样的硫醇和容易获得的伯醇和仲醇以良好至优异的产率制备各种硫醚。已证明在双键、腈、羧酸酯和卤素等敏感基团存在下的化学选择性。研究还表明,该反应是通过氢自转移(借氢)机制发生的,其中涉及 Co-Mo-S 介导的脱氢和氢化反应。使用这些地球上储量丰富的金属硫化物催化剂,还开发了一种基于醇与硫化氢 (H 2 S) 硫醚化以提供对称硫醚的新型催化方案。
