Abstract

We report a convenient access to tertiary carbinamines bearing a gem-diaryl group by Cu-catalyzed aryl Grignard addition to cyclic sulfamidate imines and sulfamide imines. The synthesis of hetero-functionalized 1,2-ethylene derivatives by ring-opening of the resulting sulfamidates is also described.

Keywords: Copper triflate, gem-diaryl group, Grignard addition, sulfamidate, tertiary carbinamine.
