Multi N-heterocyclic carbene(NHC)-modified iridium catalysts were employed in the β-alkylation of alcohols; dimerization of primary alcohols (Guerbet reaction), cross-coupling of secondary and primary alcohols, and intramolecular cyclization of alcohols. Mechanistic studies of Guerbet reaction, including kinetic experiments, mass analysis, and density functional theory (DFT) calculation, were employed
多N-杂环卡宾(NHC)-改性铱催化剂用于醇的β-烷基化反应;伯醇的二聚化(Guerbet 反应)、仲醇和伯醇的交叉偶联以及醇的分子内环化。Guerbet 反应机理研究,包括动力学实验、质量分析和密度泛函理论 (DFT) 计算,被用来解释双金属催化剂促进的快速反应,以及反应后期单金属催化剂的反应活性急剧增加。
