Novel anionic gold(I) and gold(III) organocomplexes

Abstract

Summary Tetrahydrothiophen (tht) and/or chloride may readily be displaced from ClAu(tht) with perhaloaryl lithium to give anionic complexes of the [R 2 Au] − or [RAuX] − type (R = C 6 F 5 or C 6 Cl 5 ; X = Cl or Br). Anionic gold(III) complexes can be prepared both by the reaction of Cl 3 Au-(tht) or K[AuCl 4 ] with LiC 6 F 5 or by the oxidative addition of halogens or (C 6 F 5 ) 2 TlBr to gold(I) complexes.
