Zinc Trimethylsilylamide as a Mild Ammonia Equivalent and Base for the Amination of Aryl Halides and Triflates.

We report that Zn[N(SiMe<sub>3</sub>)<sub>2</sub>]<sub>2</sub> is a mild ammonia equivalent and base for the palladium-catalyzed amination of aryl halides and triflates. In\ncontrast to LiN(SiMe<sub>3</sub>)<sub>2</sub>, the combination of Zn[N(SiMe<sub>3</sub>)<sub>2</sub>]<sub>2</sub> and LiCl coupled with aryl halides and triflates containing base-sensitive functionality\nin high yields. In addition, aryl bromides coupled with aryl and alkylamines with the combination of Zn[N(SiMe<sub>3</sub>)<sub>2</sub>]<sub>2</sub> and LiCl as base. These\naminations occurred without racemization of the enolizable stereocenter of an optically active ester.
