Article Description

The reactivity of small anionic gold clusters (Au, n = 1-4) toward small organic molecules was investigated by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). With trifluoroacetic acid (TFA) proton transfer, gold loss, and radiative association were observed. Sulfide-sulfide bond activation, sulfide-carbon bond activation, gold loss, and radiative association were observed in collisions with dimethyl disulfide (DMDS). The small gold cluster anions show a strongly size dependent reactivity, with the gold trimer being completely unreactive. Regardless of cluster size, no reaction was observed for methanol, acetonitrile, acetaldehyde, acetone, dimethyl sulfide, methyl mercaptan, benzene, ethynylbenzene, and difluoroacetic acid. © 2010 American Chemical Society.
