ZUR KENNTNIS DER ORGANOPHOSPHORVERBINDUNGEN XX. Bifunktionelle Aminophosphane (Et2N)2P-n-P(NEt2)2 und Et2N(R)P-n-P(R)NEt2

Bifunctional aminophosphanes (Et2N)2P-n-P(NEt2)2 (n = 1-10) (1) and Et2NP(R)-n-P(R)NEt2 (n = 2-4, R = Alkyl, Ph) (2), which are valuable intermediates in organophosphorus synthesis, are obtained by two methods.Because of the marked nucleophility of phosphorus in 1 and 2, reactions with Lewis acids take place very smoothly as is shown by preparation of (Et2N)2P(X)-4-(X)P(NEt2)2 (X = O, S, Se, Te, BH3, BBr3) and 4-(CH3)P(NEt2)2>2+2I-.Fission of P-N bonds by PCl3, MeOH, H2S and CS2 affords Cl2P-4-PCl2, (MeO)2P-4-P(OMe)2, (MeO)Et2NP-4-PNEt2(OMe), the dithiophosphinate 4-(H)PS2>2-2 Et2NH2+, and the dithiocarbaminate 2P-4-P2.The 31P/1H/NMR-Spectra are discussed especially with regard to steric aspects in the synthesis of the chiral compounds 2 and their derivatives.
