Unsaturated alcohols and saturated carbonyls are important chemical, pharmaceutical, and biochemical intermediates. We herein report an efficient transfer hydrogenation protocol in which conversion of unsaturated carbonylcompounds to either unsaturated alcohols or saturated carbonyls was catalyzed by Cu(I) N-donor thiolate clusters along with changing hydrogen source (isopropanol or butanol) and base
不饱和醇和饱和羰基是重要的化学,制药和生化中间体。我们在本文中报告了一种有效的转移氢化方案,其中不饱和羰基化合物转化为不饱和醇或饱和羰基的反应是由Cu(I)N供体硫醇盐簇以及变化的氢源(异丙醇或丁醇)和碱(NaOH或K)催化的。2 CO 3)。DFT过渡态建模支持的机理研究表明,这种化学选择性可以用每个催化体系中一价氢化铜(I)和质子化氢化铜(I)配合物的相对浓度来解释。
