The first bis(alkynyl)borane‐supported actinide complexes are reported. Depending on R (i.e., the B‐substituent), the bis(alkynyl)borane ligand can either coordinate in an η5‐manner, affording a six‐membered uranaboracycle, or undergo a UIV‐assisted intramolecular [2+2] cycloaddition to give a highly unusual fused bicyclic structure. More information can be found in the Communication by L. Maron, Q. Ye, et al. on page 13573.

封面人物:将硼掺入铀金属环戊烷:衍生自双(炔基)硼烷的含硼尿烷的合成,结构和反应性(Eur。J. 60/2020)

报道了第一个双(炔基)硼烷负载的act系元素配合物。根据R(即,-取代),二(炔基)甲硼烷配位体可以以任一坐标η 5 -manner,得到一个六元uranaboracycle,或经历コIV -assisted分子内[2 + 2]环加成产生非常不寻常的稠合双环结构。可以在L. Maron,Q. Ye等人的《通讯》中找到更多信息。在第13573页。
