A little bit of Ir: Methylation, one of the fundamental C−H functionalization reactions for C−C bonds construction, is developed as an efficient approach for the direct upgrading of bio-based alcohols in pure water. A selection of (bio)alcohols is selectively methylated using methanol as a sustainable C1 feedstock over small iridium clusters encapsulated within mesoporous carbon nanospheres with yolk–shell nanostructures.

碳纳米球中包裹的铱簇作为（甲基）醇甲基化的纳米催化剂

Ir：甲基化是C-C键构建的基本C-H官能化反应之一，被开发为直接纯化纯水中生物基醇的有效方法。使用甲醇作为可持续的C1原料，通过封装在具有卵黄壳纳米结构的介孔碳纳米球中的小铱簇上，选择性地选择（生物）醇进行甲基化。
