Abstract

NHC-derived selenoureas, which are useful for the quantification of NHC electronic properties, are deployed as ligands for Au(I). Surprisingly, while some compounds led to the expected [AuCl(SeUr)] species, selenoureas derived from more π- accepting NHCs unexpectedly furnished crystals of the corresponding [Au(SeUr)2][AuCl2] species in which ligand rearrangement had occurred
