Abstract
Chiral N,N'-diaryl C2-symmetric diamines and N-aryl,N'-formyl-trans-(1R,2R)-diaminocyclohexane are readily accessed by copper catalyzed N,N'-diarylation and N-aryl,N'-formylation of trans-(1R,2R)-diaminocyclohexane with aryl bromides. N,N'-diarylation using (R)-1,1'-binaphthyl-2,2'-diamine and iodobenzene gave the corresponding (R)-N,N'-diphenyl-1,1'-binaphthyl-2,2'-diamine derivative in 83% yield.
