ABSTRACT:
The invention relates to a process for nucleophilic substitution reactions. According to the invention the reaction is carried out in a heterogeneous 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%.
According to the invention the anhydrous reaction medium which is difficult to ensure, is not necessary and the use of the expensive and in industrial scales unavailable crown ethers is eliminated.
