The
effects of substituting (pseudo)halide for anionic imidate
ligands in Au(I) and Au(III) (i.e. [AuBr(NHC)] and [AuBr3(NHC)]) complexes have been investigated. [Au(N-imidate)(NHC)]
and [AuBr2(N-imidate)(NHC)] complexes
were prepared and the structure and bonding of the complexes examined
spectroscopically and crystallographically. The [AuBr2(N-imidate)(NHC)] complexes, in combination with Ag salts,
were tested for catalytic activity in the cycloisomerization of 1,5-enynes
and found to be more effective than the tribromide analogues (e.g.
[AuBr3(NHC)]). Subtle changes to the anionic imidate ligand
structure had a pronounced effect on the catalytic activity of the
Au(III) complexes.
