Bis(di-tert-butyl)-4-dimethylaminophenylphosphine

Bis(di-tert-butyl)-4-dimethylaminophenylphosphine is an organophosphine compound and can be used as an organophosphine ligand.

1. Ligand used in a highly-active palladium precatalyst for the efficient amination of aryl chloride.
2. Ligand used in the palladium-catalyzed annulations under microwave enhanced conditions.

Amphos can be used as an electrophotographic photoreceptor, process cartridge, and image forming electrode.

Ligand used to prepare a palladium dichloride catalyst (678740) on treatment with PdCl₂(COD). The catalyst effectively cross-couples aryl boronic acids with heteroaryl chlorides.
