The invention relates to a process for preparing chiral imidazolidin-2-ones of the formula I in which in which R, Rand Rhave the abovementioned meaning, with urea in the presence of an involatile ammonium salt, wherein the reaction is carried out in the presence of an aprotic polar organic solvent.

Method for the production of chiral imidazolidin-2-ones

Process for the preparation of cis-6-hexadecenoic acid

The invention relates to a process for the purification of phosphonium salts in which a solution of the crude phosphonium salt is passed over a bed of a cation exchange resin in salt form or of an adsorber resin, the resin is washed with a polar protic solvent in the case of the cation exchange resin and with an electrolyte solution and a nonpolar solvent in the case of the adsorber resin, and the phosphonium salt is eluted from the cation exchange resin with an electrolyte solution or from the adsorber resin with a polar solvent.
