2,4,6-Trichlorophenol (2) and 2,4,6-trichloro-m-cresol (5) react with calcium hypochlorite (Ca(OCl)2) in MeOH to give respectively dimer-type ketals 2-(2′,4′,6′-trichlorophenoxy)-4,4-dimethoxy-6 -chlorocyclohexadien-2,5-one (6) and 2-(3′-methyl-2′,4′,6′-trichlorophenoxy)-4, 4-di-methoxy-5-methyl-6-chlorocyclohexadien-2,5-one (7). Ketal 6, which was too unstable to be isolated, and 7 hydrolyzed in H2O/HCl to 2-(2′,4′,6′-trichlorophenoxy)-6-chloro-1,4-ben-zoquinone (8) and 2-(3′-methyl-2′,4′,6′-trichlorophenoxy)-5 -methyl-6-chloro-1,4-benzoquinone (9), respectively. Ketal 6 and quinone 8 were also produced when 2 and Ca(OCl)2 reacted in DMF, followed by addition of MeOH and H2O, respectively. The mechanisms of these reactions are examined. Conversion of the ketals and quinones to other products is described.
