Abstract
1,2,4,5-Tetrabromo-benzene and NaP(C6H5)2 (molar ratio 1 : 4) reacts in liquid ammonia under deposition of 4 moles NaBr. But instead of the expected compound 1,2,4,5-tetrakis (diphenylphosph ino) benzene, bis (diphenylphosphino)amine was formed. [(C6H5)2P]2NH was characterized by mass-, IR- and 1H-NMR-spectra and also by the reaction with chromiumhexacarbonyl.Keywords
