| 摘 要： | We synthesized and structurally characterized a novel pentanuclear gold(I) cluster by a Ag(Ⅰ)-mediated organometallic transformation.The racemic mixture of this pentanuclear gold cluster has been successfully transformed into an enantio-rich hexanuclear cluster compound by adding adscititious chiral species [Au2(S-BINAP)2]2+(S-BINAP =(S)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl).In this process,a [AuPPh3]+ species in the pentanuclear cluster is replaced by [Au2(S-BINAP)2]2+.This strategy represents a new method for the designed construction of chiral metal clusters.

| Abstract: | We synthesized and structurally characterized a novel pentanuclear gold(I) cluster by a Ag(I)‐mediated organometallic transformation. The racemic mixture of this pentanuclear gold cluster has been successfully transformed into an enantio‐rich hexanuclear cluster compound by adding adscititious chiral species [Au2(S‐BINAP)2]2+ (S‐BINAP = (S)‐2,2’‐bis(diphenylphosphino)‐1,1’‐binaphthyl). In this process, a [AuPPh3]+ species in the pentanuclear cluster is replaced by [Au2(S‐BINAP)2]2+. This strategy represents a new method for the designed construction of chiral metal clusters. |
