Journal of Organometallic Chemistry | 1986

Übergangsmetall-substituierte acylphosphane und phosphaalkene: VIII. Dicarbonylcyclopentadienyleisen-substituierte phosphaalkene mit Fe-P-einfachbindung: synthese und struktur

Lothar Weber; Klaus Reizig; Matthias Frebel; Roland Boese; Michael Polk

Abstract Phosphaalkenyliron complexes with covalent metal-phosphorus bonds are synthesized from (η5-C5H5)(CO)2FeP(SiMe3)2 and acid chlorides RC(O)Cl (R = Ph, 2,4,6-Me3C6H2, t-Bu). The molecular structure of (Z)-(η5-C5H5)(CO)2FePC(OSi-Me3)(t-Bu) is established by X-ray structure analysis.

Phosphorus Sulfur and Silicon and The Related Elements | 1992

Cycloaddition Reactions with Metallated Diphosphenes

Lothar Weber; Ewald Lücke; Matthias Frebel; Holger Bastian

Abstract Several types of cycloaddition reactions performed with metal-functionalized diphosphenes are discussed.
