ABSTRACT:
Diethers of m- or p-hydroxyphenol, as well as the monoethers, are prepared by reacting m- or p-tert.-butoxyphenol of the formula II ##STR1## with a halogen compound in the presence of a hydroxide, carbonate and/or bicarbonate of an alkali metal or alkaline earth metal and an organic solvent which is inert under the reaction conditions, at from 20.degree. C. to 150.degree. C., and, if desired, reacting the resulting diether with a dilute aqueous inorganic acid at from 30.degree. to 100.degree. C. to give the monoether.
The end products which can be prepared by the process according to the invention are useful starting materials for the preparation of dyes, drugs and crop protection agents.
