A tale of two reactions: A chromimium(salphen) complex catalyses the formation of oxazolidinones from epoxides and isocyanates. However, with particularly electron-deficient isocyanates, the complex catalyses cyclotrimerisation of the isocyanate to an isocyanurate instead (see scheme).

中文翻译:

铬(Salphen)配合物催化环氧化物和异氰酸酯合成恶唑烷酮过程中异氰脲酸酯的形成

关于两个反应的故事:铬(沙芬)配合物催化由环氧化物和异氰酸酯形成恶唑烷酮。但是,对于特别缺乏电子的异氰酸酯,该配合物反而催化了异氰酸酯向异氰脲酸酯的环三聚反应(参见方案)。
