Abstract
The invention relates to a process for nucleophilic substitution reactions. According to the invention the reaction is carried out in a hetergeneous system, consisting of a solid and a dissolved reactant, one or several organic solvents, one or several linear polyether derivatives, and/or amino compounds and water. The volume of the water is preferably at the most 100% of the volume of the organic solvent and more preferably 5%.
