14 mono-, di-, and tetranuclear palladium complexes were prepared to study the coordination chemistry of symmetrical and unsymmetrical azole-derived diimines and their anions. The diverse range of complexes obtained highlights the structural and electronic diversities imposed by these ligands. Using the monopalladium species, the electronic properties of selected bidentate ligands were determined,
制备了 14 种单核、双核和四核钯配合物,用于研究对称和不对称唑衍生二亚胺及其阴离子的配位化学。获得的各种复合物突出了这些配体强加的结构和电子多样性。使用单钯物种,通过13 C NMR 光谱确定、排序和比较所选双齿配体的电子特性,扩展 HEP2(Huynh 电子参数 2)标度的范围,甚至可以检测细微差异。此外,% V bur使用其配合物的固态分子结构确定(埋藏体积百分比)值作为某些配体的空间体积的估计值,并建立了初步的立体电子图。
Exploration of the Copper‐Catalyzed Sydnone and Sydnonimine‐Alkyne Cycloaddition Reactions by High‐Throughput Experimentation
High-Throughput-Experimentation has been used to revisit the Cu-catalyzed Sydnone-Alkyne Cycloaddition reaction. The reaction has been improved and a new click-and-release reaction has been discovered.
