    Description / Table of Contents: Cycloaddition Reactions in the System 2-Isocyanato-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane/1,1,1,5,5,5-Hexafluor-4-trimethylsiloxy-3-pentene-2-oneThe two title compounds react to give in a (3+2) cycloaddition the spiro iminophosphoran 3 and its dimer 4, respectively. The (2+2) cycloaddition of hexafluoracetone and 3 yields the oxazaphosphetane 5, which decomposes rapidely into the Staudinger product 6. The hydrolytical cleavage of the trimethylsilyl group furnishes the tricyclic phosphorane 7. The 3JPH coupling in 3 is surprisingly large (51.6 Hz).
    Notes: Die beiden Titelverbindungen ergeben in einer (3+2)-Cycloaddition das Spiroiminophosphoran 3 bzw. dessen Dimeres 4. Eine (2+2)-Cycloaddition von Hexafluoraceton an 3 läßt das Oxazaphosphetan 5 entstehen, das rasch in das Staudinger-Produkt 6 zerfällt. Über die hydrolytische Abspaltung der Trimethylsilylgruppe von 3 wird das tricyclische Phosphoran 7 erhalten. Die Kopplungskonstante 3JPH in 3 von 51,6 Hz ist überraschend groß.
