(2,4,6- tBu 3C 6H 2O)( cC 5Me 5)]P=Mn(CO) 4: Ein stabiler λ 4-Phosphandiyl-Komplex mit Phosphor-Mangan-Mehrfachbindung

Abstract

Zusammenfassung The reaction of (2,4,6- t Bu 3 C 6 H 2 O)( c C 5 Me 5 )P(CI),I, with NaMn (Co) 5 , II affords in 90% yield the terminal neutral phosphenium ion complex [(2,4,6- t Bu 3 C 6 H 2 O)( c C 5 Me 5 )]P=Mn(CO) 4 , III. III is an example of a stable λ 4 -phosphanediyl compound with a formal phosphorus manganese double bond. The synthesis and spectroscopic characterization of III are discused.
