A metal bis(trimethylsilyl)amide/Cs2CO3 co-catalyzed benzylation of in situ generated N-(trimethylsilyl) aldimines with toluene derivatives provides a diverse array of bioactive 1,2-diarylethylamines with excellent efficiency and broad functional group tolerance. The catalyst exhibits high chemoselectivity for deprotonation of toluenes at the benzylic position.
