The present invention relates to a method for purifying nucleic acids using a nucleic acid-binding phase which is furnished with a deficit of nucleic acid-binding groups A having a pK of 8 to 13, or which has groups A and binding-inhibiting groups N which are neutrally charged during the binding, and preferably during the elution, and the method comprises the following steps: (a) binding the nucleic acids to the nucleic acid-binding phase at a pH which is below the pH of the pK of the nucleic acid-binding groups A (binding pH); (b) eluting the nucleic acids at a pH which is above the binding pH (elution pH). In addition, corresponding kits and also nucleic acid-binding phases which can be used for purifying nucleic acids are disclosed. The technology according to the invention permits the purification of nucleic acids and, in particular, elution, with use of low salt concentrations, and so the purified nucleic acids can be directly processed, for example used in a PCR.

An efficient methodology for the reductivealkylation of secondaryamine with aldehyde and Et3SiH using an iridium complex as a catalyst has been developed. For example, treatment of dibutylamine with butyraldehyde and Et3SiH (a 1:1:1 molar amount of amine, aldehyde, and silane) in 1,4-dioxane at 75 °C under the influence of a catalytic amount of [IrCl(cod)]2 gave tributylamine in quantitative yield
