Palladium has proven to be effective in catalyzing the (hetero)annulation of C[double bond, length as m-dash]C bonds with ambiphilic organo(pseudo)halides. Through the employment of appropriate ambiphilic coupling partners, efficient annulation of a variety of allenes, 1,3-dienes, strained alkenes, styrenes, and other C[double bond, length as m-dash]C bond variants can be achieved to provide direct access to numerous useful hetero- and carbocyclic scaffolds. In this Feature Article, we summarize palladium-catalyzed (hetero)annulation methods reported since 2005 (spanning just over 15 years) and discuss outstanding challenges in this area of study.
事实证明,钯在催化碳-碳双键与双亲性有机(拟)卤化物的(杂)环化反应中是有效的。通过使用合适的双亲性偶联试剂,可以实现各种丙二烯、1,3-二烯、张力烯烃、苯乙烯以及其他碳-碳双键变体的高效环化反应,从而直接构建出众多有用的杂环和碳环骨架。在这篇专题文章中,我们总结了自2005年以来(跨度超过15年)报道的钯催化(杂)环化方法,并讨论了该研究领域中存在的突出挑战。
