METHOD FOR PRODUCING 2-NITROBROMBENZALDEHYDES AND 6,6'-DIBROMINDIGO |
| abstract |
The invention relates to a process for preparing 2-nitrobromobenzaldehydes by reacting dibromonitrobenzenes first with phenyllithium or butyllithium and then with a formamide derivative and to a process for preparing 6,6'-dibromindigo by addition reaction of nitromethane with 2-nitro-4-bromobenzaldehyde and subsequent treatment of the addition product with a reducing agent. |
