carbonyl–olefin metathesis (COM) reaction is a highly valuable chemical transformation in a broad range of applications. However, its scope is much less explored compared to analogous olefin–olefin metathesisreactions. Herein we demonstrate the use of tropylium ion as a new effective organic Lewis acid catalyst for both intramolecular and intermolecular COM and new ring-opening metathesisreactions. This represents
羰基-烯烃复分解 (COM) 反应是一种在广泛应用中非常有价值的化学转化。然而,与类似的烯烃-烯烃复分解反应相比,其范围的探索要少得多。在此,我们展示了将鎓离子用作分子内和分子间 COM 和新的开环复分解反应的新型有效有机路易斯酸催化剂。与最近报道的该领域的发展相比,这代表了底物范围的显着改进。

Polycyclicaromatichydrocarbons are important structural motifs in organic chemistry, pharmaceutical chemistry, and materials science. The development of a new syntheticstrategytoward these compounds is described based on the design principle of iron(III)-catalyzed carbonyl-olefin metathesis reactions. This approach is characterized by its operational simplicity, high functional group compatibility

The carbonyl–olefin metathesisreaction could facilitate rapid functional group interconversion and allow construction of complicated organic structures. Herein, we demonstrate that elemental iodine, a very simple catalyst, can efficiently promote this chemical transformation under mild reaction conditions. Our mechanistic studies revealed intriguing aspects of the activation mode via molecular iodine
