Exploiting the cooperative action of Lewis acid Zn(C6F5)2with diarylzinc reagents, the efficient arylation ofN,O-acetals to access diarylmethylamines is reported. Reactions take place under mild reaction conditions without the need for transtion-metal catalysis. Mechanistic investigations have revealed that Zn(C6F5)2not only acts as a Lewis acid activator, but also enables the regeneration of nucleophilic ZnAr2species, allowing a limiting 50 mol% to be employed.
