Abstract
To provide a process for preparing an arylamine highly selectively and highly efficiently, which is also industrially superior without a fear of a side reaction when a strong base is employed. An aryl compound having an active group is reacted with an amine compound in the presence of a base by means of a catalyst for producing an arylamine which comprises a palladium compound having a tertiary phosphine group and a phase-transfer catalyst.
Claims3
A process for producing an arylamine, which comprises reacting an aryl compound having an active group with an amine compound in the presence of a catalyst for producing an arylamine which comprises a palladium compound having a tertiary phosphine group;
- a crown ether compound;
- and a base which is selected from lithium carbonate, sodium carbonate, potassium carbonate, rubidium carbonate, cesium carbonate, sodium hydrogencarbonate, potassium hydrogencarbonate, rubidium hydrogencarbonate, potassium phosphate, magnesium carbonate or calcium carbonate.
A process for producing an arylamine, which comprises reacting an aryl compound having an active group with an amine compound selected from the group consisting of carbazoles, pyrroles, indoles and imidazoles in the presence of a catalyst for producing an arylamine which comprises a palladium compound having a tertiary phosphine group;
- a crown ether compound;
- and a base which is selected from lithium carbonate, sodium carbonate, potassium carbonate, rubidium carbonate, cesium carbonate, sodium hydrogencarbonate, potassium hydrogencarbonate, rubidium hydrogencarbonate, potassium phosphate, magnesium carbonate or calcium carbonate.
