Novel iminium compounds namely p-benzyli-dene benzyldodecyl iminium chloride (I), p-benzylidene benzylhexadecyl iminium chloride (II), p-benzylidene ben-zyloctadecyl iminium chloride (III) were prepared and characterized using FTIR, 1H-NMR and mass spectroscopy. The surface properties such as surface and interfacial tension, and biological activity of these surfactants were investigated. The surface parameters including critical micelle concentration, maximum surface excess, and minimum surface area. Efficiency and effectiveness were calculated, as well as free energies of micellization and adsorption. The prepared cat-ionic surfactants exhibit a better biological activity than the used reference cetyl trimethyl ammonium bromide.

The addition reaction between the P-H bond of tetraoxyspirophosphoranes 1-2 and long-chain imines 3a-h (decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, and oleyl imines) occurs instantaneously at room temperature. It is diastereoselective, and quantitatively leads to the corresponding (α- aminoalkyl)spirophosphoranes 4a-h and 5e. The influence of the pentacoordinated phosphorus atom on the stereoselectivity of the Pudovik reaction might be attributed to the involvement of the rigid spirophosphoranide (P(v)) intermediate in the addition reaction. Selective and one- pot hydrolysis of these P-C bond spirophosphoranes readily proceeds either at room temperature in the presence of moist solvents to give the corresponding carboxyalkyl (α-aminoalkyl)phosphonic acid monoesters 6a-h and 7e, or the reaction may be carried out in the presence of 20% aqueous hydrochloric acid under reflux, to afford the free (α-aminoalkyl)phosphonic acid amphiphiles 8a-h in high yields. In contrast to their sodium salts, these single- and double-chained free and monoester phosphonic acid amphiphiles exist as zwitterions and are not soluble in water.
A Route to Vicinal Diamines from the Samarium(II) Iodide-Mediated Coupling of Aldimines
Enholm, Eric J.,Forbes, David C.,Holub, David P.
, p. 981 - 987 (2007/10/02)
A new method to construct vicinal diamines from aldimines mediated by the one electron reductant, samarium diiodide is described.The reaction probably involves a ketyl-like radical coupling mechanism.
