A copper-catalyzed electrophilic amination of simple and functionalized aryl, heteroaryl-, benzyl, n-alkyl, sec-alkyl, and tert-alkyl diorganozinc nucleophiles with R2NOC(O)Ph and RHNOC(O)Ph reagents as electrophilic nitrogen sources provides tertiary and secondary amines, respectively, in generally good yields. In many cases, the product may be isolated analytically pure after a simple extractive workup. A Cu-catalyzed amination of Grignard reagents using cocatalysis by ZnCl2 is described.
