 Title    Darstellung Diorganylamino-substituierter Carbodiphosphorane [1] Synthesis of Diorganylamino Substituted Carbodiphosphoranes [1]  
 Abstract    Aminolysis of the P-chlorofunctional carbodiphosphorane Ph3P = C = PPI12CI (1) affords the diorganylamino substituted phosphonium salts PI13P—CH—PPh2(NR2)] + Cl~ (3a-e, R = alkyl), which can be dehydrohalogenated in good yield by NaH to give the neutral compounds Ph3P = C — PPli2(NR2) (4a-e). The structure of the hitherto unknown amino-carbodiphosphoranes has been confirmed by 31 P{ 1 H} and 13 C{ 1 H} NMR data as well as by hydrolysis to give 5, hydrochlorination to 6b, e and methylation to 7 a, e.

 Title    Darstellung symmetrisch bisaminierter Carbodiphosphorane R2NPh2P=C=PPh2NR2 [1] Synthesis of Symmetrical Diaminocarbodiphosphoranes R2NPh2P=C=PPh 2 NR2 [1]  
 Abstract    The hitherto unknown symmetrical diamino carbodiphosphoranes R2NPh2P = C — PPh2NR2 (5 a-d (R = CH3, Et, nPr, nBu) are obtained in good yield by NaH dehydrohalogenation of the corresponding aminophosphonium salts R2NPh2P^CH^PPh2NR2-i+Cl-(3a-d). 3 a-d can be prepared by aminolysis of C(PPh2Cl)2 (1) or, more conveniently, directly in the three component reaction ditertiary phosphine/amine/CCU (31 P{ 1 H} and 13 C{ 1 H} NMR).
