ABSTRACT:
Halo-displacement reaction products of aliphatic hydroxy compounds and chloro- or bromo-substituted aromatic nitrogen-heterocyclic compounds are conducted under alkaline conditions in the presence of a phase transfer catalyst, in the substantial absence of water inorganic salts other than those formed in the reaction. The method is particularly useful for the preparation of substituted chlorotriazines. In a preferred embodiment, the reagents constitute at least about 25% by weight of the organic phase of the reaction mixture.
