Ethylene is one of the most important building blocks in industry for the production of polymers and commodity chemicals. 13C‐ and D‐isotope‐labeled ethylenes are also valuable reagents with applications ranging from polymer‐structure determination, reaction‐mechanism elucidation to the preparation of more complex isotopically labeled compounds. However, these isotopic derivatives are expensive, and
乙烯是工业上生产聚合物和日用化学品的最重要组成部分之一。13C和D同位素标记的乙烯也是有价值的试剂,其应用范围从聚合物结构测定,反应机理阐明到制备更复杂的同位素标记的化合物。但是,这些同位素衍生物价格昂贵,并且是易处理的易燃气体。我们已经开发出一种方法,用于通过使用Ru催化从简单的烯烃前体中控制生成乙烯及其同位素变体,其中包括首次被完全同位素标记的乙烯。使用两室反应器既可以合成乙烯,也可以在化学转化中立即消耗乙烯,从而仅用化学计量的这两种碳烯烃即可进行反应。
