Page/Page column 8; 9, (2008/12/07)
An ionic liquid which contains an organic matter represented by the following general formula (1) as a cation component. The ionic liquid is stably in a liquid state over a wide temperature range and is excellent in electrochemical stability. The ionic liquid is advantageously used for applications such as electric power storage devices, lithium secondary batteries, electrical double layer capacitors, dye-sensitized solar cells, fuel cells, and reaction solvents.

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.
