The reactivity of π-bonded homonuclear dipnictenes [L(X)MPn]2 (M = Al, Ga, In; Pn = As, Sb, Bi) as well as heteronuclear metallapnictenes LM=PnM(X)L and L(X)M=PnR (M = Al, Ga, In; Pn = As, Sb, Bi) of heavy group 15 elements is almost unknown. This research project focuses on [2+n] cycloaddition reactions of both class of compounds. In addition, we will investigate reactions of metallapnictenes, which show polarized M‒Pn double bonds, with selected nucleophiles and electrophiles to reveal the influence of the M–Pn bond polarity on the reactivity and selectivity. We will furthermore synthesize and structurally characterize metal-rich neutral and ionic pnictogen cluster compounds, in particular bismuth clusters. Quantum chemical calculations as well as in situ 1H NMR spectroscopic studies will be systematically performed to get deeper insights into the electronic structure of the compounds as well as to identify possible reaction mechanism.

重15族元素的π-键均二镍族元素[L（X）MPn]2（M = Al，Ga，In; Pn = As，Sb，Bi）以及杂金属镍族元素LM=PnM（X）L和L（X）M=PnR（M = Al，Ga，In; Pn = As，Sb，Bi）的反应性几乎是未知的。本课题主要研究这两类化合物的[2+n]环加成反应。此外，我们将研究金属氮族化合物，这表明极化的M Pn双键，与选定的亲核试剂和亲电试剂的反应，以揭示M-Pn键极性的反应性和选择性的影响。我们将进一步合成和结构表征富含金属的中性和离子型氮族元素簇合物，特别是铋簇合物。量子化学计算以及原位1H NMR光谱研究将系统地进行，以更深入地了解化合物的电子结构以及确定可能的反应机理。
