When 5,6-benzo-1,4-dioxane was reacted with N,N-dialkylchloramines in the presence of FeSO4 at 10-20 deg C in a solution of acetic and sulfuric acids, 6-(N,N-dialkylamino)benzo-1,4-dioxanes and 6-chloro- and 6,7-dichlorobenzo-1,4-dioxanes were obtained.Under the conditions used in the study mainly chlorination products were synthesized.Reaction of 5,6-benzo-1,4-dioxane with the system (NH3OH)2SO4-TiCl3 resulted in the formation of 6-aminobenzo-1,4-dioxane.
