| titleOfInvention | Process for producing aromatic diamine compound precursor |
| abstract | Provided is a method for producing a dinitro compound, which is a precursor of a diamine compound, which is a production raw material for polyamic acid and / or polyimide, with few by-products and with high purity and high yield. It is represented by the formula (3) by reacting the aromatic dihalogen compound represented by the formula (1) and the N-alkylnitroaniline derivative represented by the formula (2) in the presence of a metal complex solvent and a base. For producing an N- (nitrophenyl) aromatic amine compound. [Chemical 1] [Ar is an arylene group or heteroarylene group; X is a halogen; R is a C 1 -C 6 alkyl] |
