Abstract

Although coupling reaction of CO with epoxides can be catalyzed by dinuclear silver complexes with low catalyst load- ing at ambient temperature and pressure, the experiment of reusability of catalyst displays the dinuclear silver complex is decomposed due to the excess Br in co-catalyst TBAB. The formed silver triphenylphosphine complex or inorganic silver materials provide real catalytic reactivity to the coupling reaction. 1·OTf +TBAB silver triphenylphosphine complex O or inorganicsilvermaterials O O CO real catalyst Keywords Green chemistry · Cycloaddition · CO fixation · Dinuclear silver complex The development of advanced technologies and chemical processes targeting to convert C O into valuable products is of great concern to scientists [1–3].
