    Description / Table of Contents: Contributions to the Chemistry of Phosphorus. 144. Synthesis and Properties of the Hexaphospha-3-germaspiro[2.4]heptane (t-BuP)2Ge(t-BuP)4The cyclocondensation of K(t-Bu)P—P(t-Bu)K with germanium tetrachloride in the molar ratio of 2:1 yields the novel spirocyclic compound 1,2,4,5,6,7-hexa-tert-butyl-1,2,4,5,6,7-hexaphospha-3-germaspiro[2.4]heptane, (t-BuP)2Ge(t-BuP)4 (1). Besides considerable amounts of (t-BuP)4 are formed and occasionally some (t-BuP)3 can be found. 1 could be isolated in the pure state and has been NMR-spectroscopically characterized as a spirocyclic compound with a P2GeP4 skeleton.
    Notes: Bei der Cyclokondensation von K(t-Bu)P—P(t-Bu)K mit Germaniumtetrachlorid im Molverhältnis 2:1 wird die neue Spiroverbindung 1,2,4,5,6,7-Hexa-tert-butyl-1,2,4,5,6,7-hexaphospha-3-germaspiro[2.4]heptan, (t-BuP)2Ge(t-BuP)4 (1), gebildet. Daneben entstehen beträchtliche Mengen an (t-BuP)4 sowie gelegentlich etwas (t-BuP)3. Verbindung 1 konnte in reiner Form isoliert und kernresonanzspektroskopisch als Spirocyclus mit P2GeP4-Ringgerüst charkterisiert werden.
