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（苯并硼烯）和硼杂环丙苯是有机硼化学的应变双环化合物，由芳香族六元环和环状三元含硼环组成。这类化合物只能在非常有限的范围内进行研究，因为长期以来在稳定基质之外不知道合成途径。由于双环框架的高环应变和硼中心的亲电性，预计对大量试剂具有有趣的高反应性，并获得新的结构基序。基于我们的前期工作，我们合成了苯并硼烯并在该项目的框架内研究了它们的化学性质。我们希望使用合适的试剂进行选定的反应，具体解决苯并硼杂环烯的反应位点（硼中心、三元环、六元环）。这将为了解此类化合物的性质以及芳香性和环张力之间的相互作用提供全面的见解。
