	Title	Neue Carbodiphosphorane. Notiz zur Reaktion zwischen Bis(dimethylamino)fluormethylidenphosphoran und /i-Butyllithium New C arbodiphosphoranes. N ote on the Reaction between Bis(dimethylamino)fluoromethylidene-phosphorane and «-Butyllithium
	Abstract	The main product from the reaction between bis(dimethylamino)fluoromethylidene-phos-phorane (1) and «-butyllithium in the presence of tetramethylethylenediamine is /j-butyl-di-methylamino-methyl-{[tris(dimethylamino)phosphoranylidene]methylene}-phosphorane (7). As a by-product from the reaction between methyl-bis(dimethylamino)difluorophosphorane and rt-butyllithium bis(dimethylamino)-methyl-{[«-butyl-bis(dimethylamino)phosphor-anylidene]methylene}-phosphorane (9) was isolated in small yield. The new carbodiphosphor anes 7 and 9 are characterized by their 'H , 13C, and 31P N M R and mass spectra.

	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).
