在我们发表了第一个二胺碳烯（DAC）负载的氨基乙烯4的合成五年后，我们现在报告了难以理解的单晶x射线结构。4的x射线结构证实了我们之前的计算研究，表明硼烯采用近线性C(carbene)= B = N单元（175.88（18）◦）的异聚几何结构，C = B和B = N距离分别为1.416(3)和1.344(3)Å。此外，我们进一步提供了关于用于制备4以及已知环（烷基）氨基卡宾（CAAC）类似物2的前体化合物的所述结构的定性和定量论述。
Five years after we published the synthesis of the first diamidocarbene (DAC)-supported amino borylene4, we now report the elusive single crystal X-ray structure. The X-ray structure of4was found to corroborate our previous computational studies which indicated that the borylene adopted a heterocumulenic geometry with a near linear C(carbene)= B = N unit (175.88(18)◦) as well as short C = B and B = N distances of 1.416(3) and 1.344(3) Å, respectively. Additionally, we further provide a qualitative and quantitative discourse on said structure with respect to the precursor compounds used to prepare4as well as to the known cyclic (alkyl) amino carbene (CAAC) analog2.
