Method for producing diphenylamine |
| abstract |
(57) [Summary] (Modified) SOLUTION: A phenol ether compound of the following formula (2) is oxybrominated to obtain a brominated phenol ether compound of the formula (3), which is subjected to Ullmann coupling conditions. Method for condensing a compound of formula (4) to give diethylamine of formula (1), using elemental bromine and carrying out oxybromination in the presence of hydrogen peroxide and, if desired, in the presence of a catalyst. I will provide a. [Effect] These diphenylamines are industrially useful intermediates, and are useful for the production of dyes and fluoran type color-developing agents for pressure- and heat-sensitive recording systems. |
