    Description / Table of Contents: Low Coordinated Phosphorus Compounds, 45. Mixed Substituted Bismethylenephosphoranes by the Reaction of Carbenoides with PhosphaalkenesThe known methylenephosphanes 1a-e react with lithio-α-chloroorganyls 2a, b to give the bismethylenephosphoranes 3a-f in high yields. The compounds 3c-f represent the first mixed substituted λ5σ3-bismethylenephosphoranes, that except 3e, f could be isolated. Products 3e, f rearrange to the new phosphiranes 6a, b. The reaction of the methylenephosphane 1b with diphenyldiazomethane (4) leads via spectroscopic conceivable dihydrodiazaphosphole 5 to compound 3e. The course of the reactions, the spectroscopic data as well as the X-ray structure analyses of 3d and 6a are discussed.
    Notes: Aus der Reaktion der bekannten Methylenphosphane 1a-e mit Lithio-α-chlororganylen 2a, b erhält man in sehr guten Ausbeuten die Bismethylenphosphorane 3a-f. Die Verbindungen 3c-f sind die ersten gemischt substituierten Vertreter der λ5σ3-Bismethylenphosphorane, die mit Ausnahme von 3e, f isoliert werden können. Die Verbindungen 3e, f lagern in die neuen Phosphirane 6a, b um. Die Reaktion des Methylenphosphans 1b mit Diphenyldiazomethan (4) verläuft über ein spektroskopisch erfaßbares Dihydrodiazaphosphol 5 zum Produkt 3e. Die Reaktionsverläufe, die spektroskopischen Daten sowie die Röntgenstrukturen von 3d und 6a werden diskutiert.
