Yield:78600-31-4 73%

Reaction Conditions:

with copper(l) iodide;18-crown-6 ether in 1,2-dichloro-benzene at 100 - 210;Inert atmosphere;Darkness;

Steps:

1 Example 1: Synthesis of N-(2-bromophenyl)-N-diphenylamine
Diphenylamine (1.6900 g, 10.0 mmol), o-dibromobenzene (2.40 mL, 20.0 mmol), copper iodide (0.1900 g, 1.0 mmol), 18-crown-6 (0.1320 g, 0.5 mmol), and 60 mL of o-dichlorobenzene were sequentially added to the reaction flask. Under nitrogen protection and dark conditions, stir and heat to 100-210°C for 5-100 hours. Stop the reaction and slowly reduce to room temperature, vacuum distillation of most of the solvent, suction filtration, The solid residue is washed with dichloromethane solution and the organic phases are combined. Concentration and column chromatography gave N-2-bromophenyl-N-diphenylamine (yield: 73%)
