“…The noteworthy feature of this complex was ''a relatively weak P-Mn interaction at 2.7651(8) Å". Crystal structure of the related zwitterion complex (CO) 3 Mn À -g 4 -(CRCRCRCRP + Me 2 ) where R = CO 2 Me had been described by Lindner et al [12], but this complex did not contain P-Mn bond.…”

In diesem Aufsatz werden Komplexe vom Typ X,M-R zusammenfassend beschrieben, in denen ein a-gebundener organischer Ligand R zusltzlich durch eine Olefin-n-Bindung rnit dem Metall M verkniipft ist. Mit anderen Worten: Die Komplexe enthalten Metallacyclen mit dreieinhalb, viereinhalb, fiinfeinhalb usw. Gliedern. Fiinfeinhalbgliedrige Ringsysteme kennt man hauptsachlich rnit 4-Pentenyl-, 1,4-Pentadienyl-, Allylnorbornyl-, Allylnorbornenyl-, Cyclooctenyl-und endo-Dicyclopentadienyl-Liganden. Metallacyclen dieser GroBe sind spannungsfrei und stabil. Donorliganden wie Amine oder Phosphane konnen die koordinierte Doppelbindung des n-Liganden vom Metall verdrangen. Diese C=C-Doppelbindung wird durch die Koordination von ca. 133 pm auf 136 bis 146 pm verlangert.

In this review article complexes of the type X,M-R are dealt with in which a a-bonded organic ligand R is additionally linked by a n-bond with the metal M. In other words, the complexes contain metallacycles with three and a half, four and a half, five and a half members, etc. Well-known five and a half membered ring systems are those with 4-penteny1, 1,4pentadienyl, norbornyl, norbornenyl, cyclooctenyl, and endo-dicyclopentadienyl ligands. Metallacycles of this size are strain-free and stable. Donor ligands such as amines and phosphanes can displace the coordinated double bond of the n-ligand from the metal. This C=C double bond is lengthened from cu. 133 pm to 136-146 pm by the coordination. 4-Pentenyl Compoundsq3-Allylcobalt complexes readily form the five and a half membered n-coordination compounds 8 by insertion of fluoroolefins into the q3-allyl-cobaltThe observation that q3-allyl(tricarbonyI)cobalt complexes already react at room temperature, whereas the phosphane-and phosphite-complexes react only on heating is explained by the electrophilicity of cobalt being lowered on bonding to the phosphorus ligand.
