The Magic of Polypnictogen Compounds


Organometallic polypnictogen compounds are an important class of compounds, valuable for many applications. Our interest is dedicated to pnictogen-rich organometallics, which usually can be synthesized from the E4 allotropes (E = P, As). Therefore, we have developed special approaches for the activation of the E4 molecules. In addition, we created novel E4-transfer reagents to avoid the handling hazardous starting materials. The talk will give an overview about the latest developments in this area[1] and the stage of the use of the transfer reagents in main group and transition metal chemistry.

Moreover, pentaphosphaferrocene, [Cp*Fe(?5-P5)], the P-rich congener of ferrocene, can be used as a starting material in different directions: (i) in redox-processes where charged anionic and cationic polyphosphorus moieties are obtained,[2] (ii) in the reaction with Cu(I) halides where nano-sized inorganic fullerene-like molecules are formed (Figure 1).
