Abstract
New N-methylimidazole-functionalized gold clusters 2 catalyze, in 6:4 metha nol-water solution, the cleavage of 2,4-dinitrophenyl acetate with more tha n an order of magnitude rate acceleration with respect to acetyl-N-methylhi stamine 3; comparison with dodecanoyl-N-methylhistamine 4 comicellized with Brij 35 reveals that 2 is still a better catalyst than the comicellar syst em and highlights analogies and differences between the two systems.
