In a joint project of the Bettinger and Wesemann working groups chemistry of low valent borylenes in matrices and solution as well as stabilized in bis(tetrylene) chelates is being explored. In a close exchange between the working groups the syntheses of the compounds are carried out. Under cryogenic conditions and in solution the reactivity of the transient borylenes and the tetrylen adducts of borylenes is investigated. The electronic structure of the low valent boron compounds and the mechanisms of their reactions is elaborated using quantum chemical calculations and discussed in an intense collaboration between the working groups. By combining the complementary approaches similarities and differences in reactivity of free borylenes and relatively weakly stabilized bis(tetrylene) adducts of borylenes are identified and further developed.

在 Bettinger 和 Wesemann 工作组的一个联合项目中，正在探索基质和溶液中的低价硼烯以及稳定在双（四萘嵌苯）螯合物中的化学。在工作组之间的密切交流中进行化合物的合成。在低温条件下和溶液中，研究了瞬态亚硼啉和亚硼啉的四联苯加合物的反应性。使用量子化学计算详细阐述了低价硼化合物的电子结构及其反应机制，并在工作组之间的密切合作中进行了讨论。通过结合互补的方法，鉴定并进一步开发了游离亚硼基和相对弱稳定的亚硼基的双(四甲苯)加合物在反应性方面的相似性和差异。
