Synthesis of Optically Active N,N,N′,N′-Tetraphenyl-1,1′-binaphthyl-2,2′-diamine Derivatives as Analogues of BINAP
摘要:
As analogues of BINAP, optically active N,N,N',N'-tetraaryl-1,1'-binaphthyl-2,2'-diamines have been prepared by palladium-catalyzed coupling reactions of optically active 1,1'-binaphthyl-2,2'-diamine with an excess amount of aryl bromides. A novel diamine-bridged dirhodium T-arene complex has been produced and characterized by X-ray analysis.
