Using readily available preallylated aldehydes, we report a simple and divergent synthesis of cyclic (alkyl)(amino)carbene (CAAC) iminium precursors. Using a combination of crystallographic data and steric maps, we further elaborate on the specific steric properties of CAAC ligands with respect to state-of-the-art phosphine and carbene ligands.
利用现成的预活化醛，我们报告了一种简单且多样化的环状（烷基）（氨基）卡宾（CAAC）亚胺前体的合成方法。结合晶体数据和空间位阻图，我们进一步详细阐述了 CAAC 配体相对于现有膦和卡宾配体的特定空间位阻性质。
