Sterically shielded primary anilides of the alkaline-earth metals of the type (thf)nAe(NH-Ar*)2 (Ae = Mg, Ca, Sr, and Ba; Ar* = bulky aryl)

Abstract

Metalation of bulky primary amines with alkaline-earth metal reagents in THF leads to primary amides, and imide formation does not occur. Coordination of THF bases competes with π-interactions with phenyl groups.
