Catalytic properties of tris(3,6-dioxaheptyl)amine (TDA-1) have been analyzed in reactions of alkoxydehalogenation of 2- and 4-chloropyridine and their N-oxides under solid-liquid phase transfer catalysis conditions. Alkoxypyridines were obtained in excelent yields but with N-oxides a competitive alkaline cleavage of the performed ether was observed.
