The goal of this work is the preparation of new interpnictogen compounds with terminal diaryl bismuth groups. These are prepared from compounds with the general
formula Ar2BiX (X = Hal), whereby Phenyl, Mesityl and 2,6-di-iso-propylphenyl substituents are used for the investigation of steric effects on the stability of the prepared compounds. Most aryl halido bismuthanes with phenyl and mesityl substituents are already described in the literature. In contrast, the Dipp substituent is introduced as a substituent for bismuth in the course of this work. Moreover, the preparation of interpnictogen compounds with Bi-N, -P, -As and -Sb bonds was studied and the reactivity of the prepared compounds evaluated.
