The reaction of benzotrichloride with 4-alkylphenols is of potential industrial importance to sythesize 2-hydroxy-5-alkylbenzophenones which are industrial oxime extractants used for extraction of copper and other metals.The attempts to obtain 2-hydroxychlorobenzophenone derivatives from 4-chlorophenol and 2,4-dichlorophenol, respectively and benzotrichloride yields besides 2-hydroxychlorobenzophenone, hydroxyketones having fewer atoms of chlorine in the aromatic ring as well as hydroxychlorobenzophenones resulting from the migration of chlorine from the para to the ortho position.In the present paper the reaction between benzotrichloride and bromophenols is studied.
