摘要

以双环己基硼烷为原料，通过选择性反马可夫尼科夫硼化反应合成了基于联苯骨架的半柔性双齿刘易斯酸。此外，还对单齿碱PMe3与吡啶、双齿碱嘧啶与双（二甲基磷酰甲基）二甲基硅烷（BisPhos）的络合作用进行了初步的主客体化学实验。双齿双磷被发现经历螯合型络合，而嘧啶以不同的方式络合形成类似于单齿碱的1:1加合物。采用单晶x射线衍射和溶液核磁共振光谱对主-客体配合物进行了表征。

Synthesis and Reactivity of a Semi-Flexible Bidentate Poly-Lewis Acid Based on Biphenylene

Semi-flexible bidentate Lewis acids based on the biphenylene backbone were synthesized by selective anti-Markownikow hydroborations using dicyclohexylborane. In addition, initial host-guest chemistry experiments were carried out on the complexation of the monodentate bases PMe₃ and pyridine, as well as the bidentate bases pyrimidine and bis(dimethylphosphanylmethyl)dimethylsilane (BisPhos). The bidentate BisPhos is found to undergo a chelate-type complexation, whereas pyrimidine is complexed in a different manner forming a 1 : 2 adduct analogous to the monodentate bases. The host and all host-guest-complexes were characterized by single crystal X-ray diffraction, and in solution by NMR spectroscopy.
