 Title    Synthese amino-und silylsubstituierter Triphosphane -Struktur des des etraphenyl-2-tri-fStf-propylsilyl-triphosphans Synthesis of Amino-and Silyl-Substituted Triphosphines -Structure of 1.1.3 .3 -Tetraphenyl-2 -tri-/s0 -propylsilyl-triphosphine  
 Abstract    A variety o f triphosphines [(Et2N)2 P]2PR 4 a -h , [('Pr2 N)2P]2PR 5 a -e and [Ph,P]-,PR 9 e -g [R = Cy (a), rBu (b), Mes (c), M e3Si (d), 'BuM e2Si (e), ThexM e2Si (f), 'Pr3Si (g), Äd"(h), H (i)] has been obtained by the reaction o f the dilithiated primary phosphines R PH 2 l a -h with 2 equiv. o f the chlorophosphines (Et2 N)2PCl 2, ('Pr2N)2PCl 3 or Ph2PCl 8 . M ethanolysis o f the trimethylsilyl substituted derivative [('Pr2 N)2 P]2P(SiM e3) 5d yields the hydrogen substituted triphosphine [('Pr2 N)2 P]2PH 5i. The lithiated diphosphine ('Pr2 N)2 P -P (S iM e 3)Li 6 reacts with the chlorophosphine 2 to give the unsymmetrically substituted triphosphine ('Pr2N)2 P -P (S iM e 3)-P (N E t2) 2 7d. The com pounds have been chracterized by their N M R and mass spectra. The structures o f 4d and 9g have been determined by X-ray diffraction, repre­ senting the first structures o f uncomplexed triphosphines.
