Aim of this research project is (i) the synthesis of hitherto unknown heavy pnictogen biradicals of the type type [E(NR)]2 (E = Sb, Bi) and the unprecendented (oxidized) monoradical cations of the type [E(NR)]2+[wca]- (E = P, As, Sb, Bi; wca = weakly coordinating anion), (ii) the activation of small molecules bearing single bonds by biradicals of the type [E(NR)]2 (E = element of group 15), (iii) the activation of small molecules bearing double bonds by biradicals of the type [E(NR)]2 (E = element of group 15), (iv) the activation of small molecules bearing triple bonds by biradicals of the type [E(NR)]2 (E = element of group 15), and (v) exploration of the reactivity of [E(NR)]2 biradicals towards Lewis bases and -acids and N-heterocyclic carbenes. We want to demonstrate, that new classes of cage compounds and heterocycles can be generated by activation of small molecules. This study will be accompanied by a combined experimental and theoretical work with respect to (vi) structure, bonding and reactivity depending on the elemente E and the substituent R.

该研究项目的目的是（i）类型[E（nr）] 2（E = SB，BI）类型的迄今未知的沉重的pnictogen Biradicals和未经预言的（氧化的）单自动阳离子的类型[E（nr）] 2+ [WCA] 2+[WCA] 2，E = P，e = P，sb，sb，sb，sbiivity; molecules bearing single bonds by biradicals of the type [E(NR)]2 (E = element of group 15), (iii) the activation of small molecules bearing double bonds by biradicals of the type [E(NR)]2 (E = element of group 15), (iv) the activation of small molecules bearing triple bonds by biradicals of the type [E(NR)]2 (E = element of group 15）和（v）[E（nr）] 2对刘易斯基地和 - 酸和N-杂环碳纤维的反应性的探索。我们要证明，可以通过小分子的激活来产生新的笼子化合物和杂环。这项研究将伴随（VI）结构，键合和反应性，具体取决于元素和取代基。
