    Description / Table of Contents: Contributions to the Chemistry of Phosphorus. 226. 2,3,4,6-Tetra-tert-butyl-2,4-dioxobicyclo[3.1.0]hexaphosphane, P6Bu4tO2Under suitable conditions, the reaction of tetra-tert-butylhexaphosphane, P6Bu4t (1), with cumene hydroperoxide gives rise to the corresponding dioxide P6Bu4tO2 (3) which could be isolated as the adduct P6Bu4tO2 · 0.7 C9H12O2. According to a complete analysis of the 31P{1H}-NMR spectrum compound 3 is 2,3,4,6-tetra-tert-butyl-2,4-dioxobicyclo[3.1.0]hexaphosphane, in which the oxygen atoms are bonded exocyclically to the five-membered phosphorus ring of 1. When the oxidation reaction proceeds a fission of the bicyclic P6 skeleton takes place.
    Notes: Die Reaktion von Tetra-tert-butylhexaphosphan, P6Bu4t (1), mit Cumolhydroperoxid führt unter geeigneten Bedingungen zu dem entsprechenden Dioxid P6Bu4tO2 (3), das als Addukt P6Bu4tO2 · 0,7 C9H12O2 isoliert werden konnte. Nach einer vollständigen Analyse des 31P{1H}-NMR-Spektrums handelt es sich bei 3 um 2,3,4,6-Tetra-tert-butyl-2,4-dioxobicyclo[3.1.0]hexaphosphan, in dem die Sauerstoffatome exocyclisch an den Phosphor-Fünfring von 1 gebunden sind. Bei fortschreitender Oxydation findet eine Spaltung des bicyclischen P6-Gerüstes statt.
