Reactions of gold(I) compounds with carbon monoxide to form gold clusters and fulminates

Au(I) compounds of the type AuPPh3X, where X is a weak coordinated ligand like NO3-, ClO4-, BF4-, or OAc-, react with carbon monoxide to form gold clusters of the type Au9(PPh3)8X3. The carbon monoxide is transformed to CO2, probably via initial binding to gold. A precursor of the gold clusters could be detected in a AuPPh3NO3 matrix. When CH2Cl2 is used as a solvent, carbon monoxide and AuPPh3NO3 or Au9(PPh3)83+ give a complicated reaction resulting in the formation of fulminates. In this way AuPPh3CNO and Au11(PPh3)8(CNO)2+ are synthesized. Key in the formation of fulminate is the reaction of a reactive intermediate, probably AuPPh3NO, with CH2Cl2. 13CO-labeling experiments confirm the origin of the carbon in the fulminate to be CH2Cl2.
