Boracyclopropabenzenes (benzoborirenes) and boratacyclopropabenzenes are strained bicyclische compounds of organobor chemistry that are comprised of an aromatic six membered and an annulated three membered boron containing ring. This class of compounds could only be investigated to a very limited extend because a synthetic access was not known for a long time outside of stabilizing matrices. Due to the high ring strain of the bicyclic framework and the electrophilicity of the boron center interesting and high reactivity towards a large number of reagents and access to novel structural motifs is expected. Based on our preliminary work, we synthesize benzoborirenes and study their chemical properties in the framework of the project. We wish to address specifically the reactive sites of the benzoborirenes (boron center, three-membered ring, six-membered ring) using selected reactions with suitable reagents. This will provide comprehensive insight into the properties of this class of compounds and the interplay between aromaticity and ring strain.

硼体现丙苯甲苯（苯并核烯）和硼酸丙吡啶甲苯是有机体化学的紧张的甲环丙烷化合物，由有机体化学的化合物组成，由芳香族六个成员组成，并环绕的三个含有三个成员的硼含环。这类化合物只能进行非常有限的扩展研究，因为在稳定矩阵之外长期以来，合成的访问尚未闻名。由于双环框架的高环应变以及硼中心的亲电性，对大量试剂的反应性以及对新型结构基序的访问感也很高。根据我们的初步工作，我们合成了苯并核烯并研究其在项目框架中的化学特性。我们希望使用具有合适试剂的选定反应来专门针对苯并核烯（硼中心，三元环，六元环）的反应位点。这将为这类化合物的特性以及芳香族性和环应变之间的相互作用提供全面的见解。
