Substitution Reactions of Phenylated Aza-Heterocycles. Part 2. Bromination of Some 2,5-Diaryl-1,3,4-oxadiazoles

Electrophilic bromination of the title compounds may be achieved using either bromine in oleum, or bromine and potassium bromate in a sulphuric-acetic acid mixture.Under the milder reaction conditions provided by the latter, 2-(p-nitrophenyl)-5-phenyl-1,3,4-oxadiazole (2), the model compound used in this study, is mono- and di-brominated in the phenyl ring.In the first bromination step, all three monobromo-isomers are produced in appreciable amount.The orientation of the second bromination is controlled entirely by the first bromine and not by the oxadiazole substituent: this is confirmed by a separate study of the bromination of the three monobromo-compounds (3a-3c).
