    Description / Table of Contents: The Behavior of Mono- and Diorganylphosphine Sulfides towards Metal Carbonyl Systems, XII. The Isomerization of Secondary Phosphine Oxides on Carbonyl(halogeno) Metal Complexes of Manganese and RheniumSecondary phosphine oxides R2HPO (R = C6H5 (2a), CH3 (2b)) can be transformed into the complex-stabilised phosphinic acids R2POH on the pentacarbonyl(halogeno)manganese and -rhenium systems XM(CO)5 (4, 5). In contrast to the extremely labile O-isomers (CO)4XReOPHR2 (3) the P-isomeric manganese and rhenium compounds (CO)4XMPR2OH (6, 7) are very stable. The IR, Raman, 1H, and 31P NMR spectra are discussed.
    Notes: Die sekundären Phosphinoxide R2HPO (R = C6H5 (2a), CH3 (2b)) lassen sich gemäß Gl. (2) an den Pentacarbonyl(halogeno)mangan- bzw. -rhenium-Systemen XM(CO)5 (4, 5) in die komplexstabilisierten phosphinigen Säuren R2POH überführen. Die P-isomeren Mangan- und Rhenium-Komplexe (CO)4XMPR2OH (6, 7) sind gegenüber den außerordentlich labilen O-Isomeren (CO)4XReOPHR2 (3) sehr beständig. Die IR-, Raman-, 1H- und 31P-NMR-Spektren werden diskutiert.
