We report on the effect of small side-chain modifications to the structure of 3,3-dimethyl-1-(trifluoromethyl)-3H-1λ3,2-benziodaoxole (1b) on its reactivity, as expressed by the initial rate v0 in a model reaction, and show how the latter can be successfully correlated to an easily determined physical parameter p, a 13C NMR chemical shift. The relationship v0 ~ p is already present in the simplest
我们报告了小侧链修饰对 3,3-二甲基-1-(三氟甲基)-3H-1λ3,2-benziodaoxole (1b) 结构的影响,如初始速率 v0 在 a模型反应,并展示后者如何成功地与易于确定的物理参数 p(13C NMR 化学位移)相关联。关系 v0 ~ p 已经存在于没有高价键和碘核心的最简单的起始材料中,因此,为此类试剂的未来支架优化提供了一种有趣的方法。
