 Title    Phosphinsubstituierte Chelatliganden, III [1] r/ 5 -Cyclopentadienyleisencarbonyl-Koraplexe mit Thiocarbamoylphosphin-, -phosphinsulfid-und -phosphinoxid-Liganden Phosphine Substituted Chelate Ligands, III [1] r/ 5 -Cyclopentadienyliron Carbonyl Complexes with Thiocarbamoyl-Phosphine, -Phosphine Sulfide and -Phosphine Oxide Ligands  
 Abstract    The reactions of N-silylated and free diphenylphosphino thioformamides, Ph 2 PC(S)NRR' (R = Ph, Me, Et; R' = MeaSi, H), with CpFe(CO)2l yield, by displacement of one equiva-lent CO, both red-brown P,S-coordinated chelate complexes 1 a-c and green P-coordinated iodo complexes 2a-c. With thiocarbamoylphosphine sulfides, Ph 2 P(S)C(S)NHR (R — Ph, Me), the S,S'-coordinated chelate complexes 3a, b are obtained. The corresponding phos-phine oxides only form deeply coloured, weak 1/1 adducts 4a, b with CpFe(CO)2l. The course of the nucleophilic substitution of CpFe(CO) 2 X (X = Cl, Br, I) by N-silyl phos-phino thioformamides reveals a significant dependence on the halogen employed. For X = Cl, elimination of RNCS and formation of the cationic diiron complex [CpFe(CO)2]2~ PPh2 + Cl _ (5 a) takes place, whereas forX = Brno reaction occurs at room temperature. Mechanistic reasons for this unexpected behaviour are discussed.

 Title    Synthese neuer Phosphan-und Fluorophosphankomplexe durch Ligandmodifikation in der Koordinationssphäre von kationischen Cyclopentadienyleisen-bis(phosphan)-Komplexen  
 Abstract    Synthesis o f New P hosphane and F lu o ro p h o sp h an e Com plexes by Ligand M odification in the C o o rd in atio n Sphere o f C ationic C yclopentadienyliron B is(phosphane) Com plexes H an s Schum ann* 3 und Liliana E gurenb The reaction o f nitrile solvate complexes [(C5H 5)(P(O C H 3)3)2(N C C H 3)Fe]PF6 (la) and [(C5H 5)(D PPE)(N C C H 3)Fe]PF6 (lb, DPPE = [(C6H 5)2PCH 2]2) with halogenophosphanes, -ar-sines or -stibines L' afford the cationic complexes [(C5H 5)(L2)(L')Fe]PF6 (II, L-, = (P(O C H 3)3)2, L' = PC13, P(CH3)C12, P(/-C4H9)C12, P (Q H 5)C12, P(C6H 5)2C1, PBr3, AsC13, SbCl3; III, L2 = D PPE, L' = PC13, A sCl3, SbCl3) in high yield. Spectroscopic data are given together with the characterization o f [(C5H 5)(P(OCH3)3)2(P(r-C4H9)Cl2)Fe]PF6 (lie) by single crystals X-ray dif­ fraction analysis. Through reduction o f coordinated P —Cl ligands in selected com plexes II and III complexes bearing PH3, P(C6H 5)H 2 and P(C6H 5)2H ligands are available. With anhydrous K F in acetonitrile solution in the presence o f dibenzo-18-crown-6, the coordinated P -C l li­ gands in selected complexes II and III undergo Cl/F-exchange with form ation o f related com ­ plexes with P(CH3)C1F, P(CH3)F 2, PF2C1 and PF3 ligands.
