The regiospecificity of hydroxylation of C2-halogenated phenols by Rhodococcus opacus 1G was investigated. Oxidative defluorination at the C2 position ortho with respect to the hydroxyl moiety was preferred over hydroxylation at the non-fluorinated C6 position for all 2-fluorophenol compounds studied.
