    Description / Table of Contents: 1-Methyl-1-methylene-1λ5-phosphorinane and Cyclopropyl(dimethyl)methylenephosphorane: Two Different Types of Ylides from an Analogous Reaction, and their ComplexesThe reaction of NaNH2 with (4-bromobutyl)- or (3-bromopropyl)-trimethylphosphonium bromide in THF under reflux yields the two title compounds 1 and 8, resp. At room temperature imide-bridged double ylides 2 and 10 are generated. The reaction path is interpreted. With copper, silver, and gold(I) chloride, the dimeric coinage metal complexes of these ylides are obtained. In the first case (with 1) the complexes are assigned a double spirocyclic structure (7a-c).
    Notes: Die Reaktion von NaNH2 mit (4-Brombutyl)- oder (3-Brompropyl)-trimethylphosphonium-bromid in siedendem THF liefert die beiden Titelverbindungen 1 bzw. 8. Bei Raumtemperatur entstehen imid-verbrückte Doppel-Ylide 2 bzw. 10. Der Reaktionsverlauf wird gedeutet. Mit Kupfer-, Silber- und Gold(I)-chlorid werden die dimeren Münzmetall-Komplexe der Ylide erhalten, denen im ersteren Fall (mit 1) eine doppelt spirocyclische Struktur zukommt (7a-c).
