    Perfluormethyl‐Element‐Liganden. XLIII [1] Neue Synthesewege zu Zweikernkomplexen des Typs MM′(CO) 8 ER 2 X (M/M′ = Mn/Mn, Mn/Re, Re/Re; E = P, As; R = CF 3 , Me; X = Hal)
    摘要:
    Mn(CO)(5)I reacts with compounds of the type (CF3)(2)EASMe(2) (E = P, As) as with the symmetric E-2(CF3)(4) ligands in the first step with cleavage of the E-As bond to yield the products (CO)(5)MnE(CF3)(2) and Me2AsI. Reaction of the mononuclear complexes with excess of Mn(CO)51 leads in good yields to the known dinuclear compounds (CO)(4)Mn[E(CF3)(2,)I]Mn(CO)(4) and CO. Me2AsI, the second product of the EAs cleavage, attacks the starting compound Mn(CO)(5)I giving cis-Mn(CO)(4)I(AsMe2I) and CO. This result encouraged us to thoroughly investigate the preparation of cis-M(CO)(4)X(EMe2Y) complexes with most of the possible combinations of M = Mn, Re; E = P, As and X,Y = Cl, Br, I. An alternative route to these compounds was opened by the cleavage of the dinuclear manganese or rhenium halides M-2(CO)(8)X-2 with the halophosphanes or -arsanes Me2EY This route was found to be especially advantageous for the preparation of the rheniumcarbonyl precursors, since milder conditions than for the CO-substitution in Re(CO)(5)X compounds are sufficient for the halogen-bridged dinuclear complexes.Cis-M(CO)(4)X(EMe2Y) complexes were used as precursors for the synthesis of novel homo- and heterodinuclear complexes of the type (CO)(4)M(EMe2,X)M'(CO)(4) by reacting the EY function with transition metal carbonylates Kat[M'(CO)(5)] (Kat = Na, Bu4N Ph4As). Thus the preparation of a wide range of complexes was possible, which before had been successfully prepared by the direct reaction of Mn-2(CO)(10) with Me2EX only in few cases, c. g. with Me2AsI. Spectroscopic investigations, using the CO valence frequencies and the H-1-NMR data of the ligands EMe2Y or of the Me2E bridges, were applied to study the influence of the variables M, M', E, X, Y and Kat on the reactivity of the mononuclear complexes and the bonding situation in both the mono- and the dinuclear systems. The new compounds were characterized by spectroscopic (IR, NMR, MS) and analytic methods (C, H).
