Autor: Herbert W. Roesky, Mathias Noltemeyer, Reinhard Hasselbring, Michael Witt, M. Rietzel

Publikováno v: Phosphorus, Sulfur, and Silicon and the Related Elements. 72:209-215

Various routes have been developed to synthesize mono-, di- and trisilylated derivatives of the phosphazenium salt [H2NPPh2NPPh2NH2]∗Cl− (1) in moderate to good yields. The trisilylated phosphazene compound 6 has been characterized by X-ray struc

The reactions of [[graphic omitted])Cl3] with Ph3SiOH and ButOH lead not to the expected substitution products but to exchange and rearrangement reactions in which the nitrogen atoms which co-ordinate molybdenum are replaced by oxygen. The crystal st
