 Title    Ein weiteres 2A5,4A5-Diphosphapyridin: 2,2,4,4-Tetrakis-(dimethylamino)-6- amino-l-aza-2A5,4A5-diphosphinin  
 Abstract    A Further 2A5,4A5-Diphosphapyridine: 2,2,4,4-Tetrakis-(dimethylamino)-6-amino-1-aza-2A5,4A5-diphosphinine.-(dimethylamino)-6-amino-l-aza-2A5,4A5-diphosphinine (3) has been pre­ pared by reacting l,l,3,3-tetrakis(dim ethylam ino)-lA 5-3A:'-diphosphete (1) with bis(trimethyl-silyl)carbodiimide (2) in a 2 : 1 molar ratio. Properties, 'H, P, and l3C NMR, mass, and IR spectra are reported and discussed. Com pound 3 is further characterized by X-ray structure analysis.

 Title    6-Pyridyl-l-aza-2A5,4/.5-diphosphinin - ein 2,2'-Bipyridin-Analogon 6-Pyridyl-l-aza-2/l5,4/l5-diphosphinine - a 2,2'-Bipyridine Analogue  
 Abstract    -Tetrakis(dimethylamino)-lA5,3A5-diphos-phete, (1), reacts with 2-cyano-pyridine to yield 6-pyridyl-l-aza-2/l5,4A5-diphosphinine (3). 3 is cha­ racterized by its 'H , 31P, and 13C NMR, mass, and IR spectra as well as the results of the X-ray struc­ ture analysis.
