 Title    Elementorganische Amin/Imin-Verbindungen, XIX [1] Phospha(III)azen-Komplexe des Platins Elementorganic Amino/Imino Compounds, XIX [1] Phospha(III)azene Complexes of Platinum  
 Abstract    Reacting Zeise's salt with the phospha(III)azene (R3C)(R3Si)N-P = N-CR3 (R = CH3) (1) one gets the platinum phospha(III)azene complex (2), Cl2PtI<2 (L = 1). 2 adds water and methanol to the P=N bond of the phospha(III)azene ligand with formation of 3, Cl2Pt(PRR2 1)2 (R = (CH3)3SiO, R 1 = (CH3)3CNH) and 4, Cl2Pt(PRR 1 R 2)2 (R = CH30, R 1 = (CH3)3CNH, R2 = (CH3)3SiNC(CH3)3). 2, 3 and 4 have trans configuration, 4 also forms a mixture of the meso and d, 1 isomers. For 2 a P-a coordination of the phospha(III)-azene ligand is proposed. Die inzwischen in größerer Anzahl bekanntge-wordenen Phospha(III)azene des Typs A [la] /Py -W X N-A I

 Title    (CH2OCH3)P(C6H5)2N(CH3)R * mit chiralen Fe-Atomen Optically Active Transition Metal Complexes, LXX [1] Preparation of the Optically Active Diastereoisomers CsHsFe^O)- (CH2OCH3)P(C6H5)2N(CH3)R* with Chiral Fe Atoms  
 Abstract    The two diastereoisomers CsHsFe(CO)(CH2OCH3)P(CeHs)2N(CH3)R* (Ba, b), with R* = 0S)-CH(CH3)(C6H5), differing only in the Fe configuration, have been obtained by photochemical reaction of C5H5Fe(C0)2CH20CH3 with (£)-(+)-P(C6H5)2N(CH3)R*. The optically pure isomer 3 a can be isolated by chromatography at low temperature; its chiroptical properties are discussed.
