Application

This oxaziridine has been used in synthetic methods for amination, heteroatom transfer, and C-H functionalization. Recently, the lab of Laszlo Kurti demonstrated its application for direct electrophilic primary and secondary amination of arylmetals in the presence of Cu(I) salts -- void of precious metal catalysts, ligands, protecting groups, or directing groups.

Site-selective C-H functionalization has emerged as an attractive tool for derivatizing complex synthetic intermediates, but its use for late-stage diversification is limited by the functional groups that can be introduced, especially at unactivated sp(3)-hybridized positions. To overcome this, we introduce

Arylmetals are highly valuable carbon nucleophiles that are readily and inexpensively prepared from aryl halides or arenes and widely used on both laboratory and industrial scales to react directly with a wide range of electrophiles. Although C-C bond formation has
