Abstract

Owing to the high reactivity of the carbon–carbon triple bond, alkynes can react with various reagents to give functionalized alkenes and alkanes, making it a useful compound to build complex molecules. Herein, we reported a one-pot, two-step strategy which use arenes and alkynes as the reactant combined with carbon monoxide to afford α, β-unsaturated esters. The transformation goes through iodonium ions intermediate and proceed under mild conditions, a series of the target products were generated in good to excellent yields.

端炔和芳烃生成α， β-不饱和酯的四组分羰基化反应

由于碳碳三键的高反应活性，炔烃可以与各种试剂反应得到功能化的烯烃和烷烃，使其成为构建复杂分子的有用化合物。在此，我们报道了一锅，两步的策略，使用芳烃和炔烃作为反应物与一氧化碳结合得到α， β-不饱和酯。在温和的条件下，通过碘离子中间体进行转化，得到了一系列收率较高的目标产物。

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.
