Description
Abstract
The oxidation of compounds of the type XAu(dpe)AuX [dpe = l,Z-bis(diphenylphosphino)
ethane] leads to organogold(II1) complexes. When X is Cl,
treatment with BrTl(C,F,), leads to oxidative addition of two C6 FS groups to
each gold atom and formation of CI(C,F,)2 Au(dpe)Au(& F5)* Cl, which by
metathesis with KBr or KI gives the corresponding bromo (or iodo) derivative.
When X is C6 FS oxidation with halogens leads in the case of X’ = Cl or Br to
formation of Xi (C, FS )Au(dpe)Au(& F5 )X; whereas, for X’ = I reductive elimination
of I&F5 takes place to give IAu(dpe)AuI.
