A general method for the hydrogenation of quinones to hydroquinones under atmospheric pressure has been developed. In the presence of [Cp*Ir(2,2'-bpyO)(HO)] (0.5-1 mol %), a range of products were obtained in high yields. Furthemore, the expansion of this catalytic system to the hydrogenation of 1,4-benzoquinone diimines was also presented. Functional groups in the bpy ligand were found to be crucial for the catalytic activity of iridium complexes.
已开发出一种在大气压下将醌氢化为对苯二酚的通用方法。在[Cp*Ir(2,2'-bpyO)(HO)]（0.5 - 1摩尔%）存在的情况下，一系列产物以高产率获得。此外，还展示了该催化体系扩展至1,4 - 苯醌二亚胺的氢化反应。发现bpy配体中的官能团对铱配合物的催化活性至关重要。
