 Title    Preparation and Reactions of Bicyclic Compounds with a Phosphorus-Phosphorus-Bond  
 Abstract    The reaction of N,N'-dimethyl-N,N'-bis(trimethylsilyl)urea with PCI3 leads to the bicyclic compound OP2[MeNCONMe]2 (3) with a direct phosphorus-phosphorus bond and to the bicycle MeNP2[MeNCONMe]2 (4). 3 reacts with tetrachloro-o-benzoquinone (TOB) to yield the spirocycle CeCl^tMeNCONMe^PaO (5) with a A 4 P-A 5 P-bond. The Lewis acids SbCls and SnCLj react with 3 to give the adducts 6 and 7. The reactions of 3 with the metal carbonyls Fe2(CO)9, Cr(CO)5THF and Cr(CO)4C7Hx lead to the metal complexes 8-10. The compounds were characterized on the basis of 31 P NMR and mass spectra. Kürzlich haben wir gezeigt, daß Reaktionen von disilylierten Harnstoffen mit Dichlorphosphanen,

 Title    Darstellung von trans-[PtCl4Br2] 2 -und [PtClsBr] 2 - durch oxidative Addition an [PtCl4] 2 ~ Preparation of Jrarwi-[PtCl4Br2] 2 -and [PtCl5Br] 2 -by Oxidative Addition to [PtCl4] 2 ~  
 Abstract    The oxidative addition of Br2 to [PtCl4] 2-in HBr yields almost pure frans-[PtCl4Br2] 2-, in HCl nearly pure [PtClsBr] 2-, and in CH2C12 by a quantitative and stereospecific reaction completely pure £ram-[PtCl4Br2] 2 ~. This is confirmed by ion exchange chromatography on diethylaminoethyl cellulose and by analysis of the vibrational spectra in comparison with the IR and Raman spectra of the well-known species of the series [PtClnBr6-n] 2_ , n = 0-6. The literature concerning £rans-[PtCl4Br2] 2 ~ and other mixed ligand complexes is critically discussed.
