Cyclobutenes are highly useful synthetic intermediates as well as important motifs in functional molecules. Herein, we report a straightforward access toward monosubstituted cyclobutenes from cyclopropyl N-tosylhydrazone. 1,2-Aryl or -alkyl shift of the Rh(II) carbene intermediate plays the key role in this transformation.

Rh(II)-催化环丙基 N-甲苯磺酰腙扩环生成 1-取代环丁烯

环丁烯是非常有用的合成中间体,也是功能分子中的重要基序。在此,我们报告了从环丙基N-甲苯磺酰腙直接获得单取代环丁烯的方法。Rh(II) 卡宾中间体的 1,2-芳基或 - 烷基转移在这种转化中起着关键作用。
