Using an analogous method to that of Brust et al.,13 an aqueous solution of sodium tetrachloroaurate is added to a toluene solution containing 3 and tetraoctylammonium bromide (as phase transfer reagent), followed by slow addition of excess NaBH4. A dramatic colour change from red to dark purple\/black is noted and a black powder is isolated from the organic layer. This material is entirely consistent with the known properties (i.e., UV\/Vis, etc.) of thiol-derivatised (i.e. 3 containing) Au nanoparticles.
