 Title    Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, I Metallorganische Komplexe von Mangan und Rhenium mit zwei funktionellen Zentren Preparation and Properties of and Reactions with Organometallic Heterocycles, I Organometallic Complexes of Manganese and Rhenium with two Functional Centres  
 Abstract    The binuclear anions Na2[(0C)4MP(0)R2]2 (2a, a', b, b') [M = Mn: R = CH3 (a), C6H5 (a'); M = Re: R = CH3 (b), CßHs (b')] can be obtained quantitatively by reduction of the phosphinic acid complexes (OC)4BrMP(OH)R2 (la, a', b, b') with sodium amalgam in ether. While the manganate anions 2 a, a' can be transformed with excess sodium into the mononuclear salts Na2[(0C)4MnP(0)R2] (3 a, a'), with two nucleophilic centres, the corresponding anions 2 b, b' eliminate CO to give sparingly soluble species. From 3 a, a' and dimethylsulphate the doubly methylated compounds CH3Mn(CO)4P(OCH3)R2 (4a, a') are obtained. The rhenium derivatives CH3Re(CO)4P(OCH3)R2 (4b, b') are formed only in very poor yields from 2 b, b' and dimethylsulphate under reductive conditions. The IR, *H NMR, and mass spectra are discussed.
