摘要

有人提出并完成了在常压下将对位醌甲酰胺的 1,6-共轭氢化反应转化为二芳基和三芳基甲烷。在[Cp*Ir(2,2′-bpyO)(H2O)]（0.5 摩尔%）存在下，可以高产率获得一系列理想的产物。研究发现，铋配体中的官能团对铱配合物的催化活性至关重要。此外，还介绍了本催化体系的实际应用。

1,6-Conjugate hydrogenation of para-quinone methides to phenol-containing diaryl- and triarylmethanes under atmospheric pressure catalyzed by a metal–ligand bifunctional iridium catalyst

The 1,6-conjugate hydrogenation of para-quinone methides to diaryl- and triarylmethanes under atmospheric pressure has been proposed and accomplished. In the presence of [Cp*Ir(2,2′-bpyO)(H₂O)] (0.5 mol %), a range of desirable products were obtained in high yields. Functional groups in bpy ligand were found to be crucially important for the catalytic activity of iridium complexes. Furthermore, the practical application of the present catalytic system was also presented.

期刊介绍： The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes. The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods. The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
