Abstract
A method for the production of a fluorinated phenylenediamine is provided which comprises steps of reacting a diamide represented by the following formula with NaOCl at a molar ratio of the NaOCl to the diamide in the range of 2.0-6.0 and NaOH at a molar ratio of the NaOH to the diamide in the range of 1.8-6.0 is provided. According to this invention, the fluorinated phenylenediamine can be produced conveniently in a high yield.
Claims12
A method for the production of a fluorinated phenylenediamine represented by the following formula (2), which comprises steps of reacting a diamide represented by the following formula (1) with NaOX [wherein X stands for a bromine atom (Br) or a chlorine atom (Cl)] at a molar ratio of the NaOX to the diamide (NaOX/diamide ratio) in the range of 2.0-6.0 and NaOH at a molar ratio of the NaOH to the diamide (NaOH/diamide ratio) in the range of 1.8-6.0.
- wherein in the formulas (1) and (2), Y stands for a hydrogen atom (H), a bromine atom (Br), a chlorine atom (Cl), a fluorine atom (F), a C1-C5 alkyl group optionally having a substituent, or a C1-C5 alkoxyl group optionally having a substituent, 1 is an integer in the range of 1-4, m is an integer in the range of 0-3, provided that the total number of 1 and m (1+m) is 4.
