Abstract:
1. A process for the preparation of guanidinium salts of the formula (1) in which the substituents R in each case, independently of one another, have the meaning of hydrogen, straight-chain or branched alkyl having 1-20 C atoms, saturated, partially or fully unsaturated cycloalkyl having 3-7 C atoms, which may be substituted by alkyl groups having 1-6 C atoms, where one or more substituents R may be partially or fully substituted by halogen or partially by CN or NO where up to four substituents R may be bonded to one another in pairs by a single or double bond and where a carbon atom or two non-adjacent carbon atoms of one or more substituents R may be replaced by atoms and/or atom groups selected from the group —O—, —C(O)—, —C(O)O—, —S—, —S(O)—, —SO A by reaction of a compound of the formula (2)  in which the substituents R have a meaning indicated for formula (1) and X denotes F, Cl or Br, with a compound of the formula (3)  in which A where R″ in each case, independently of one another, denotes phenyl or a linear or branched alkyl group having 1-6 C atoms, which maybe substituted by phenyl, and subsequent reaction of the resultant compound of the formula (4)  where the substituents R, X and A  where the substituents R have a meaning indicated for formula (1) and M denotes hydrogen, R″
