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.

本研究项目的目的是（i）合成迄今未知的[E（NR）]2型重氮族双自由基（E = Sb，Bi）和未被取代的[E（NR）]2+[wca]-型（氧化）单价阳离子（E = P，As，Sb，Bi; wca =弱配位阴离子），（ii）通过[E（NR）]2型双自由基活化带有单键的小分子（E =第15族元素），（iii）通过[E（NR）]2型双自由基活化带有双键的小分子（E =第15族元素），（iv）通过[E（NR）]2型双自由基活化带有三键的小分子（E =第15族元素）;（v）探索[E（NR）]2双自由基对刘易斯碱和-酸以及N-杂环卡宾的反应性。我们想证明，新类别的笼状化合物和杂环可以通过活化小分子来产生。这项研究将伴随着一个结合的实验和理论工作方面（六）结构，键和反应性取决于元素E和取代基R。
