Experimental And Theoretical Investigations Of The Bromination Of Phenols With Beta And Gamma Aliphatic Substituents, Including Rings

Bromination reactions of substituted and ring fused phenols were studied by both experiment (t-BuNH-Br) and computation (density functional theory). The outcomes support each other, indicating a clear and predictable regioselective preference among 3,4-bis-alkylated and 3,4-ring-fused phenols.
