Oxidative addition of chlorine to dinuclear N-heterocyclic dicarbene gold(I) complexes of formula [Au-2(RIm-Y-ImR)(2)](PF6)(2) (R = Me, Y = (CH2)(1-4); R = Cy, Y = CH2) affords in high yield stable Au(III)/Au(III) and Au(II)/Au(II) complexes. The nature of the products depends on the bridge between the two carbene moieties. With Y = methylene, ethylene and butylene, Au(III)/Au(III) dinuclear dicarbene complexes are formed. Only in the case of the propylene bridge the main product is an Au(II)/Au(II) complex. The same reaction output is now proposed also in the oxidative addition of bromine, as fully supported by the X-ray structure of complex [Au2Br2(MeIm-(CH2)(3)-ImMe)(2)](PF6)(2). (C) 2012 Elsevier B.
