HCID 128743633-(4-Bromophenoxy)benzaldehyde

Procedure

9.60 Grams (0.060 mole) of bromine were added dropwise to 9.90 g (0.050 mole) of m-phenoxybenzaldehyde at 0° C. taking a period of 1 hour with vigorous stirring. After the addition was finished, the reaction was continued for a further 3 hours at the same temperature. The unreacted bromine was distilled off under reduced pressure from the reaction system to obtain m-(p-bromophenoxy)benzaldehyde (No. 9 in Table 2).
