Paragraph 0098; 0140; 0141; 0215, (2018/03/25)
In one aspect, the present disclosure provides methods of preparing a primary or secondary amine and hydroxylated aromatic compounds. In some embodiments, the aromatic compound may be unsubstituted, substituted, or contain one or more heteroatoms within the rings of the aromatic compound. The methods described herein may be carried out without the need for transition metal catalysts or harsh reaction conditions.

Herein we disclose a novel method for the facile transfer of primary (-NH2) and secondary amino groups (-NHR) to heteroaryl-as well as arylcuprates at low temperature without the need for precious metal catalysts, ligands, excess reagents, protecting and/or Erecting groups. This one-pot transformation allows unprecedented functional group tolerance and it is wellsuited for the amination of electron-rich, electron-deficient as well as structurally complex (hetero)arylmetals. In some of the cases, only catalytic amounts of a copper (l) salt is required.
