Despite that electrophilicity parameters have now been established for more than 250 reactive species, the corresponding parameters for benzyne and related intermediates have not been uncovered. We report a study that has allowed for the quantification of benzyne's electrophilicity parameter. Our approach relies on the strategic use of the diffusion-clock method and also provides electrophilicity parameters
短寿命中间体反应参数的确定为合成设计提供了不可或缺的工具。尽管现已确定了 250 多种活性物质的亲电参数,但苯炔和相关中间体的相应参数尚未被发现。我们报告了一项研究,该研究可以量化苯炔的亲电性参数。我们的方法依赖于扩散时钟方法的策略性使用,并且还提供其他取代芳炔的亲电性参数 E。
