Abstract

[reaction: see text] An efficient catalytic system for oxidant-free oxidation of alcohols has been developed. A new CpIr catalyst bearing a 2-hydroxypyridine ligand has been designed on the concept of "ligand-promoted dehydrogenation". Various secondary alcohols can be dehydrogenatively oxidized to ketones under neutral conditions with high turnover numbers by using the new CpIr catalyst.

摘要

[反应：见正文] 已开发出一种用于醇类无氧化剂氧化的高效催化体系。基于“配体促进脱氢”的概念设计了一种带有2-羟基吡啶配体的新型CpIr催化剂。使用这种新型CpIr催化剂，各种仲醇在中性条件下可通过脱氢被氧化为酮，且具有高的周转数。
