posted on 2024-02-26, 13:06 authored by Jin Zhang, Xiangchao Xu, Guoqiang Zhao, Heng You, Rongzhou Wang, Feng LiA general method for the hydrogenation
of quinones to
hydroquinones
under atmospheric pressure has been developed. In the presence of
[Cp*Ir(2,2′-bpyO)(H2O)] (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.
