in the ligand are crucial for the activity of catalyst and selective transfer hydrogenation is the determining step of the formation of alkenyl ketones as products. Notably, the present research exhibited also the unique potential of metal–ligand bifunctional catalysts for the activation of unsaturated alcohols as electrophiles for hydrogen auto-transfer process.
一种用于链烯基酮的合成策略经由所述α酮与烯基酮烷基化已提出并实现的。在金属-配体双功能催化剂[Cp*Ir(2,2'-bpyO)(H 2 O)]的存在下,以高产率获得了一系列理想的产物。机理研究表明,配体中的官能团对催化剂的活性至关重要,选择性转移氢化是形成烯基酮产物的决定性步骤。值得注意的是,本研究还展示了金属-配体双功能催化剂在活化不饱和醇作为氢自动转移过程的亲电试剂方面的独特潜力。
