4-Halophenol derivative → Hydroquinone derivative<br>4-Halobenzoate derivative → 4-Hydroxybenzoate derivative<br><br>Comments:<br>This rule handles hydrolytic dehalogenation of 4-halogenated benzoates and oxidative dehalogenation of 4-halogenated phenols. Halobenzoate derivatives add CoA to form the thioester before dehalogenation but this step is bypassed for simplification.
