Benzaldehyde → 3-Bromobenzaldehyde

Participants

Reaction Steps

Into a mixture of 1,2-dichloroethane (1,2-dichloroethane: 173.7 g, 1-bromo-2-chloroethane: 63.5 g, 1,2-dibromoethane: 2.2 g) and recovered from Example 1 with 98% aluminum chloride (0.365 mol, 88.6 g) was blown chlorine (0.25 mol, 17.8 g) at 25° C., and 97% benzaldehyde (0.50 mol, 54.6 g) was added over 1 hour at 40° C. After bromine (0.30 mol, 48.0 g) was added dropwise to this mixture over 2 hours at 40° C., the resulting mixture were stirred for 2 hours at that temperature. The post-treatment was carried out by the similar procedure to that in Example 1. As a result, 82.8 g of 3-bromobenzaldehyde were obtained.
