Abstract

Carbonyl–olefin metathesis reactions are powerful transformations for carbon–carbon bond formation. Despite recent progress, limitations exist that hamper the synthetic generality of the reported approaches. Catalytic systems that will enable tuning of their Lewis acidity and consequently the selective activation of specific substrate classes are expected to greatly enhance the current scope. We herein report the development of cationic iron-bis(oxazoline) complexes as powerful catalysts that enable the alteration of Lewis acidity to efficiently convert substrate types that were previously found to be incompatible with existing catalytic systems in carbonyl–olefin ring-closing metathesis.

双（恶唑啉）铁配合物调节催化羰基-烯烃复分解的刘易斯酸度

羰基-烯烃复合反应是碳-碳键形成的有力转化。尽管最近取得了进展，但存在一些限制，妨碍了所报告方法的综合普遍性。催化系统将能够调整其刘易斯酸度，从而选择性激活特定的底物类别，预计将大大扩大目前的范围。我们在此报道了阳离子铁-二（恶唑啉）配合物的发展，作为强大的催化剂，可以改变刘易斯酸度，有效地转化底物类型，这些底物类型在羰基-烯烃闭环复分解中被发现与现有的催化体系不相容。
