A neat reaction: A ring‐closing metathesis (RCM) strategy is presented in which the two termini of a light, and thus volatile, isotopically labelled olefin are held separate by way of a higher molecular weight diene component, allowing synthetic manipulations to be conducted without difficulty. Using simple laboratory apparatus, a solvent‐free catalytic RCM process can be achieved that avoids side
简洁的反应:提出了一种闭环复分解(RCM)策略,其中轻质的,因此易挥发的,同位素标记的烯烃的两个末端通过较高分子量的二烯组分分开保持,从而可以进行合成操作没有困难。使用简单的实验室设备,可以实现无溶剂的催化RCM工艺,从而避免了副反应,并可以分离出高纯度的烯烃。
