Abstract: The synthesis and reactivity of the novel cyclotetraphosphane [ClP(μ-PMes*)]2 were studied. The cyclophosphane proved to be a versatile reagent in phosphorus chemistry, since its Cl-functionalised P4 backbone could be used as a building block in a variety of reactions with Lewis acids, bases as well as reducing agents. The rearrangement of P−P bonds as well as a 1,2-Cl shift were identified as common reaction pathways to stabilise the products. All synthesised compounds were fully characterised, including experimental and theoretical methods.

Die Synthese und Reaktivität des neuartigen Cyclotetraphoshans [ClP(μ-PMes*)]2 wurden untersucht. Das Cyclophosphan stellte sich als vielseitiges Reagenz in der Phosphorchemie heraus, da sein Cl-funktionalisiertes P4-Rückgrat als Baustein in einer Vielzahl von Reaktionen mit Lewis-Säuren und -Basen sowie Reduktionsmitteln Anwendung finden konnte. Die Umlagerung von P–P-Bindungen sowie eine 1,2-Cl-Umlagerung wurden als typische Reaktionspfade zur Stabilisierung der Produkte identifiziert. Alle hergestellten Verbindungen wurden vollständig charakterisiert. [German]
