    Description / Table of Contents: Cis-1-Phosphabicyclo[4.3.0]nonanecis-1-Phosphabicyclo[4.3.0]nonane has been synthesized by free-radical cyclization of 4-phophino-octa-1.7-diene. The bicyclic phosphine is characterized by reactions with CS2, Ni(CO)4, HSO3F, CH3I, H2O2, sulfur, and selenium, respectively. The determination of the relative configuration of the phosphine is done by a qualitative conformational analysis from the 13C n.m.r. data.
    Notes: Durch radikalische Cyclisierung von 4-Phosphino-octa-1,7-dien erhält man cis-1-Phosphabicyclo [4.3.0]nonan, das durch Reaktionen mit CS2, Ni(CO)4, HSO3F, CH3I, H2O2, Schwefel und Selen charakterisiert wird. Die Bestimmung der relativen Konfiguration des Phosphins erfolgt durch eine qualitative Konfigurationsanalyse aus den 13C-NMR-Daten.

    Description / Table of Contents: 5-Hydroxy-1-phosphabicyclo[3.3.1]nonaneA new approach to 1-phosphabicyclo[3.3.1]nonane compounds involves free-radical cyclization of 4-trimethylsilyloxy-4-phosphinomethyl-hepta-1.6-diene synthesized by the reaction of 2.2-diallyl-oxirane with KPH2 followed by trimethylsilylation. Trimethylsilyl groups are easily cleaved in boiling methanol forming 5-hydroxy-1-phosphabicyclo[3.3.1]nonanes. Silylated and desilylated bicyclic compounds are characterized by n.m.r. and i.r. data.
    Notes: Die Reaktion von 2,2-Diallyl-oxiran mit KPH2 zu 4-Hydroxy-4-phosphinomethyl-hepta-1,6-dien, das nach Bildung des Trimethylsilylethers radikalisch cyclisiert wird, stellt einen neuen Zugang zum 1-Phosphabicyclo[3.3.1]nonan-System dar. Die Titelverbindung wird durch Abspaltung der Trimethylsilylgruppe in siedendem Methanol gebildet. Die silylierten und entsilylierten bicyclischen Verbindungen werden durch NMR- und IR-Daten charakterisiert.
