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.

硼杂环丙苯（benzoborirenes）和硼杂环丙苯（boratacyclopropabenzenes）是有机硼化学的应变双环化合物，其由芳族六元和成环的三元含硼环组成。这类化合物只能在非常有限的范围内进行研究，因为在稳定基质之外的很长一段时间内都不知道合成途径。由于双环框架的高环应变和硼中心的亲电性，预期对大量试剂和获得新的结构基序的有趣和高反应性。在前期工作的基础上，我们在本项目的框架下合成了苯并硼烯并对其化学性质进行了研究。我们希望具体解决的反应位点的苯并硼（硼中心，三元环，六元环）使用选择的反应与合适的试剂。这将提供这类化合物的性质和芳香性和环应变之间的相互作用的全面了解。
