organic transformations. We demonstrate that observed product ratios in [4 + 3]/[4 + 2] cycloisomerization processes are influenced by both steric and electronic properties of the phosphine, which can be represented by the Au–Cl distance. In contrast, the observed selectivity of a similar [2 + 3]/[2 + 2] cycloisomerization is governed by L/B1, a steric parameter. Using this correlation, we were able
在这里,我们报告了简单的线性回归与
金(I)催化的整合,以询问
磷化氢结构对
金属催化的有机转化的影响。我们证明,在[4 + 3] / [4 + 2]环异构化过程中观察到的产物比率受膦的空间和电子性质的影响,这可以用Au-Cl距离表示。相反,观察到的相似的[2 + 3] / [2 + 2]环异构化的选择性受空间参数L / B1支配。使用这种相关性,我们能够准确地预测以前未经测试的布赫瓦尔德型
配体的选择性,以提高相同转化的选择性。该
配体在将先前报道的
金催化的1,6-烯炔的环异构化/芳基化的选择性提高〜1 kcal / mol方面具有进一步的实用性。
